Body & Chassis Parts Range Rover 4.0 / 4.6 /P38A
Tailgate & Hood Struts
Tailgate Strut: Aftermarket replacements for the tailgate strut are available at SpeedyCarParts.com (click on "Rover" parts) for $27. I recently (October 2004) found it was even less at British Pacific (their part number ALR10050) for $24.25. I recently found (October 2004) that Atlantic British trumps all comers in this category with a price of $29.95 for the pair!!
Hood strut: The genuine part allows locking of the hood in the position and costs a lot -- well over $50. SpeedyCarParts.com have a low cost non-locking replacement for the hood strut for $26.24.
Grille:
I discovered that the genuine radiator grille is now available from Atlantic British for $189.
Rear View Mirror:
Paul Smail of Annapolis MD reports "I have twice replaced the auto-dimming mirror in my Range Rover. A couple of years ago I purchased a comparable replacement directly from Donnelly (OE manufacturer) after being quoted nearly $700 for a genuine replacement. The ersatz replacement cost around $250 and was supposedly better constructed, using some sort of gel photochromic matrix rather than the liquid in the original mirror, plus it had a nifty compass! Notwithstanding this new technology, the replacement mirror waited just until it was out of warrantly to fail. Have since purchased a genuine parts replacement from The Rover Connection out in Utah for a price comparable to that of a Magna-Donnelly replacement. The Rover Connection also have mirrors for other model Land Rovers in the $250 price range.
Wing/Fender:
The easily-damaged front fender or wing is now available from aftermarket suppliers such as Atlantic British, who have it in stock for $459.95.
Braking System Range Rover 4.0 / 4.6 /P38A
ABS Accumulator:
Most suppliers do not seem to list this part separately, but I did find it at Rovers North for $326. SpeedyCarParts.com (click on "Rover" parts) lists new units for $239 with free shipping. Recently, (October 2004) I found it at British Pacific (STC2784) for only $199.99!
ABS Pump:
This component is so expensive that most suppliers don't seem to even list it. I did find it at Rovers North for $1075, but the lowest price I have found so far is at British Pacific, who have it for $999.
Calipers & Caliper Repair Kits:
When the calipers start leaking, the new ones (especially for the front) cost over $300 each, or you can get rebuilt ones (eg Rovers North has them for about $141 each for the front ones, and partsamerica.com has them for about $135). Alternatively, you can easily rebuild them yourself, using an aftermarket caliper rebuild kit that includes all the seals -- I found one for the 4.0/4.6 at SpeedyCarParts.com (click on "Rover" parts) for only $41 for the front brakes and $29.97 for the rear. I also found one for the front brakes at British Pacific (STC1919) for $15.99, who also have rear kits (STC1909) for $26.95. Atlantic British does not have the front kits but has one for the rear for only $14!
Caliper Guide Pin Kits
A more common problem than worn out or leaking calipers is frozen caliper guide pins, which you will notice when you try to do a brake job. I shopped around and found Atlantic British has them for $28.95 (front axle set) and $26.95 (rear axle set) including new pins, rubber boots and special lubricant.
Pads:
Part Numbers: Front STC3685, Rear STC3684. Dealer Price (Oct 2004) approx $180 per axle set.
Atlantic British offers several aftermarket brake pad options from $44.95 to $130 for front pad sets and $32.95 to $100 for rear sets. British Pacific stocks the genuine front pads (SPF100460G) for $69.95 and the well-known Ferodo aftermarket brand for $44.95 (SPF100460). For the rear pads, they stock two options -- SPF100470F for $59.95 SPF100460P for $39.95.
The lowest prices from Rover aftermarket specialists for the front pads seem to be British Pacific (SPF100460) Ferodo brand pads and Atlantic British Lockheed brand pads (made in the UK) for $44.95.
For the rear pads, I thought the record was held by SpeedyCarParts.com (click on "Rover" parts) for Deluxe PBR brand pads for $35.78. (Their options for the front include $70 for Mintex and $96 for OEM Lucas pad sets). However, Atlantic British now (October 2004) offers the highly respected Lockheed brand rear pads for only $32.95!!
If you want to try a real generic part (not really advisable when it comes to brakes in my opinion!), you can try the Wagner rear pads I found at AutoPartsGIANT.com for $26.00 or the rebuilt "Wearever Silver" ones from partsamerica.com for $11.48 -- if you attempt this please let me know the results!!
Parking Brake Shoes:
I have not seen these listed in mail order catalogs but SpeedyCarParts.com (click on "Rover" parts) has them for $121 for a set with free shipping.
Rotors/Discs: The extra weight and speed of the 4.0/4.6 models is hard on brakes an they seem to wear out the rotors rapidly. The stock front brake rotors are $81 from Rovers North, but aftermarket units are now available. The lowest prices I have seen after searching many sources are the following:
Front: SpeedyCarParts.com (click on "Rover" parts) Brembo front vented discs for $65 each (their rear ones are $46). Atlantic British has aftermarket front rotors for $50.95.
Rear: Atlantic British has rear rotors for $41.95 each.
Climate Control Range Rover 4.0 / 4.6 /P38A
A/C Compressor & Clutch:
The compressor/clutch assembly is now about $500 from discount mail order houses such as Atlantic British, which is a bit lower than prices for the Classic equivalent. In October 2003, Alan Rawson reported finding a company in Abilene, TX that rebuilds compressor clutches and has a stock of other parts. Hancock Industries (
http://www.hancockindustries.com/) sold Alan a rebuilt AC clutch for $110 (+$50 core). It turned out to be very easy to take the old one off his '96 4.6HSE and slip the new one on w/o disturbing the AC charge--it only took courage dealing with the unknown. They sell a complete (rebuilt?) compressor w/clutch for $250 ($75 core). The parts had no written instructions since they are intended for professional AC shops, but John, in the Hancock rebuild shop, was extremely helpful in explaining how the clutch was mounted and what to do in getting it off, how to set the air gap. I did find a generic replacement for the clutch bearing at partsamerica.com for $42.99 (retail cost given as $129).
Please email me if you find any other low cost generic replacement for the A/C compressor or parts thereof.
A/C Condenser Unit:
This is a very expensive item to replace. I found aftermarket versions of the condenser only at Atlantic British for $429.95, or the complete unit with fans for $949.95. SpeedyCarParts.com has the complete assembly (Valeo brand) with fans for only $772.94.
A/C Receiver/Drier:
I found this item for $119.95 from Atlantic British. I also found it (October 2004) in stock at SpeedyCarParts.com (click on "Rover" parts) for $83.97 with free shipping! If you wish to try a generic solution, the Ready Aire 4086 is listed for the 4.0/4.6 by partsamerica.com for only $61.99!
Climate Control Head Unit:
The control panel and ECU that is the mastermind of the 4.0/4.6 climate control system usually costs about $600 even at aftermarket parts suppliers I have searched. I was therefore pleasantly surprised to find it at Car Cannibal for only $395 exchange, for models with or without heated seats, whether the problem with yours is display readout failure or complete malfunction.
Expansion Valve:
Until recently I was never able to locate a low cost source for this part; it was not even listed in the catalogs I tried. The usual replacement part is about $180, but recently (October 2003) I finally found a generic replacement (Egelhof brand) for only $34.79 at SpeedyCarParts.com.
Blend/Flap Motors:
These motors that control air distribution from the heater body are a common failure item (see heater blend motor diagnosis and replacement page). Atlantic British stocks the set of three with the harness (STC3259) for $199. The lowest cost I have seen for them to date (October 2004) is at SpeedyCarParts.com where they have them for $175 (free shipping). The separate blend motor for the fresh air/recirc flaps (mounted to the blower motors behind the extreme left and right fasia vents) can be had for $109 at Atlantic British (STC3266). You should also be able to use this part to replace any single one of the other blend motors insteatd of all three, and splice the leads into the wiring harness.
Heater Core:
This component (STC3261) does not fail as readily as on the Classic, but eventually it does. Unfortunately it is a more expensive part than the old Classsic version. SpeedyCarParts.com has it for $369, and I found the genuine part available at Atlantic British for $339.95.
3-Way Pressure Switch:
This vital component (which attaches to the receiver/drier and makes sure the system pressure is within prescribed limits before it allows the compressor to be turned on) failed on mine (see A/C problems section) and the A/C blew hot air. I found you can now get a replacement at SpeedyCarParts.com for only $82.
Cooling System Range Rover 4.0 / 4.6 /P38A
Belt (Serpentine):
The lowest price I have seen for the serpentine belt (1995-98) after searching many catalogs and websites is $19.99 at British Pacific (ERR4460).
For 1999-02 models, the lowest price I have seen (October 2004) is $22.99 at British Pacific
Belt Tensioner Assembly:
This is a known weak point on the 4.0/4.6. The price of a replacement from Rovers North is now down to $81.52; this seems to be the lowest price currently available (October 2004) if shipping costs are not counted. SpeedyCarParts.com lists an replacement for $87 with free shipping, which would probably work out cheaper overall.
Expansion Tank Cap:
Atlantic British has these (ESR1480) for only $21.95, guaranteed to fit.
Fan Blades
I found these at SpeedyCarParts.com for only $103. Atlantic British lists an aftermarket design, slightly different from the original, for $79.95.
Hoses:
For the radiator top hose (usually the first to go as it is the hottest), aftermarket replacements average about $11. A Gates replacement part #20357 is listed at AutoPartsGIANT.com for $7.82. The lowest price I have ever seen (October 2004) is at Partsamerica.com which has a Drive-Rite brand generic replacement (curved, cut to fit) for $5.99!!
Radiator:
95-98 Models: I found new OEM and aftermarket radiators for 95-98 models (genuine part equivalent PCC106940 for VIN numbers to WA410481) at SpeedyCarParts.com (click on "Rover" parts) for $423 with free shipping. Radiator.com did offer a replacement for $445 but recently they changed their website and I find it too difficult to navigate. The lowest price I have been able to find after searching high and low is at Atlantic British who now list them (February 2005) for $349.95. (To find it, do a search for "radiator" under RR 4.0/4.6 in all categories or the engine category on their website).
99-02 Models: The radiator for the later Bosch engine models is part number PCC106850. SpeedyCarParts.com has them for $394.92 with free shipping, and the lowest cost source I have seen is British Pacific for $389.
Thermostat:
On 4.0/4.6 engines the thermostat is a large, expensive item in a separate housing with several hoses connected to it. After searching many sources (October 2004) I found the best deals at British Pacific which has them for $87.50, and at Atlantic British who have them for $79.95 plus shipping.
Viscous Fan Clutch:
As of October 2004 the cost of the 4.0/4.6 viscous fan clutch is $229 at Rovers North, who also sell an aftermarket versionn for $209. The best deal I can find for this part after searching multiple sources is at Atlantic British for $183.95.
Water Pump:
SpeedyCarParts.com (click on "Rover" parts) have these for $162 (free shipping). Atlantic British now lists an aftermarket water pump for the 4.0/4.6 for $155.
The lowest price I have seen to date is an A1 Cardone brand unit (try at your own risk -- let me know of your experience) for $148 with free shipping at ExpressAutoparts.com.
Update August 2004: The Rover Connection has just announced that they have water pumps for all 4.0/4.6 RR models for $89!!
Water Pump Gasket:
I found a British made generic replacement for this at SpeedyCarParts.com for only $6.52.
Water Temperature Sender:
This sensor that drives the temperature gauge is not as expensive as on early Classics. Aftermarket versions are available at reasonable prices; SpeedyCarParts.com (click on "Rover" parts) sells one for $22 (listed in their "Body Electrical" category, not Cooling System!).
Cruise Control Range Rover 4.0 / 4.6 /P38A
Vacuum Pump:
This item is a fairly expensive one to replace. Even at aftermarket suppliers like Atlantic British it is $404.95. However, I recently (October 2004) found a replacement at SpeedyCarParts.com (click on "Rover" parts) for $150.53 (Body Electrical parts category).
Electrical Range Rover 4.0 / 4.6 /P38A
Alternator:
New Alternators: Dealers charge anything up to $700 for new alternators. Rovers North has aftermarket "ProLine" versions now for $399, and SpeedyCarParts.com has brand new Marelli alternators for the 4.0/4.6 for $365.62. The lowest price I have found for new alternators is at British Pacific which offers new alternators for $314.99 (AMR4247 -- 1995 to mid 97) and $349 (AMR2938 -- mid 97 through 98). These two models seem to be interchangeable. The part for 1999 on is ERR5834, but aftermarket suppliers do not seem to offer it yet.
Rebuilt Alternators: The Rover Connection has these for $220 but with a rather massive $150 core charge! AutoPartsGIANT.com has several options for rebuilt units, with the lowest cost one being only $142! SpeedyCarParts.com (click on "Rover" parts) has rebuilt100 amp Bosch units for $220.86 (October 2004). Partsamerica.com lists an Autolite remanufactured alternator for $211.99.
The lowest price I have found for rebuilt alternators is $142 (free shipping) at AutoPartsGIANT.com, which also has a couple of other brands to choose from.
Battery:
Brian Weaver reports that the replacement battery for the 4.0/4.6 is an Interstate Commercial
battery, the 29H-VHD. It retails for $80.95. Here's a link to it at Interstate's website.
Fuse Box:
Unfortunately this is a failure item on the 4.0/4.6 (see the fusebox problem & repair page for ways you might be able to fix yours to avoid replacement). I recently found (Novemner 2004) that Import Parts Bin/Speedy Car Parts stock new fuse boxes for the 4.0/4.6 (1995-98) for $216.71 with free shipping. (Click on "Rover" parts -- body electrical). They also have the 1999 & up fusebox for $164.17 with free shipping. Atlantic British has replacements for prices nearly as low -- $224.95 for 1995-98 and $169.95 for the later Bosch controlled engines (1999 & up).
Headlight Bulbs:
Sylvania lists their part number 9003 for low beam replacement, (with 9003CB for an upgrade), and 9005 for the high beam. For the auxiliary headlights, they list the H3 55W bulb.
The 9003 (Wagner) is listed for $9.03 at ExpressAutoparts.com. and both the Sylvania 9003 and 9005 (high beam) are $8.49 at partsamerica.com. They also list a General Electric H155 high/low beam bulb for $7.59, among many other alternatives and upgrades.
Fog Lights:
H3 55W
Relays:
Most relays on the 4.0/4.6 are Siemens parts.
Starter Motor:
The costs of aftermarket and rebuilt starters for the 4.0/4.6 have come down recently (October 2003). The Rover Connection has them for $350.
The lowest pricse I have seen for new starters are at Atlantic British who have brand new ones for $199.95 plus shipping, and SpeedyCarParts.com who have new ones for $195.30 with free shipping. British Pacific has them (check with them whether new or rebuilt but I think they are new) for $189.00 plus shipping.
Rebuilt Bosch starters for the 4.0/4.6 by Orange County Alternator are available from AutoPartsGIANT.com for $206. Ampere Automotive brand rebuilt starters are available from ExpressAutoparts.com for $178.83. The lowest price I have seen for rebuilt ones is $145 from The Rover Connection (plus a core charge).
Engine Mechanical Range Rover 4.0 / 4.6 /P38A
Camshaft & Rocker Shaft Components:
SpeedyCarParts.com has camshafts for $233 with free shipping, cam followers for $11, rocker shafts for $78, and rockers for $7.
Engine Long Block:
I recently discovered that Car Cannibal offers complete rebuilt 4.6 engine long blocks including, if you wish, a mildly enhanced cam for more power and torque) for only $4,000.
Head Gaskets:
The 4.0/4.6 is unfortunately notorious for blowing head gaskets. I still recall talking to an owner of a brand new 2000 model who had just had this happen on his.The good news is that replacements, made by Elrin, the OEM supplier to Land Rover, are available for only $10 each at SpeedyCarParts.com! (Click on "Rover" parts). They also have a complete set of all required gaskets for a head gasket job for only $128.90! Head gaskets in all these sets are composite material with steel reinforced head bolt and cylinder bore holes.
Intake Manifold Gasket:
This is an item that has had to be replaced innumerable times at considerable expense on my 4.0SE. I recently found out that SpeedyCarParts.com (click on "Rover" parts) stocks the intake manifold valley gasket for only $11!
Main and Rod Bearings:
Aftermarket rod bearings are now available from Atlantic British for $84.95 per set. I found a British-made set of 4.0/4.6 rod bearings at SpeedyCarParts.com (click on "Rover" parts) for only $39. Their main bearings are $82 per set with free shipping.
Timing Chain:
An aftermarket timing chain is available from Atlantic British for $50. SpeedyCarParts.com (click on "Rover" parts) has it for $36. The timing cover gasket needed if you are doing this job is $10.84 from the same supplier.
Exhaust System Range Rover 4.0 / 4.6 /P38A
Catalytic Converters:
These are expensive items to replace, and all 4.0/4.6 models have a single piece Y pipe with both converters that comes as a single unit. The genuine part number is ESR4095 for model years through 97 (cost so high you are afraid to ask). With this in mind, Atlantic British developed their own replacement for this part using quality aftermarket cats and stainless steel pipes. This should last longer than the genuine part, and is priced at $699.95. The Rover Connection lists an aftermarket replacement for the Y pipe and cats for $550. SpeedyCarParts.com lists the combined Y pipe and converters in stock (49 state) for $504.67 (with free shipping, which is a significant factor on such a bulky item).
The lowest price I have seen to date is at Discount Converters Ltd of Houston, Texas, which lists a 49-state replacement part number ROVqq09 for the 4.0/4.6 that includes both left and right converters for $432.95 plus shipping, and a 50 state system for $489.95 plus shipping.
Complete Cat-Back Exhaust Systems:
I found a complete cat-back replacement exhaust system at Atlantic British for about $400 -- a savings even on discount aftermarket pricing for the separate items (see below). aftermarket Borla makes a performance enhancing exhaust system for the 4.0/4.6, available through Atlantic British for $799. Northwest Rover Performance is also working on a system for the 4.0/4.6. Note that these high performance systems can increase noise and resonance at certain speeds.
Mufflers, Center and Rear:
(For full details on replacement of the center and rear mufflers, and the parts needed, see the 4.0/4.6 muffler replacement page)
Center Muffler:
The genuine center muffler and associated tubing is available from The Rover Connection for $185. One is now available from British Pacific (ESR3195, MY 95-97) for $179 and from Atlantic British for the same price. Atlantic British carries the largest selection of 4.0/4.6 exhaust replacement options I have seen, including stainless steel replacements with lifetime warranties.
Rear Muffler(s)
1995-96: Up through 1996 there was only one rear muffler -- the genuine part ESR3538 is $260 from The Rover Connection. The lowest price I have seen so far is for a replacement from Atlantic British for $239.
1997-2002: For these model years there were two rear mufflers. The genuine complete tailpipe/muffler assembly ESR4126 retails for about $400, but can be ordered from The Rover Connection for $280. The lowest price I have seen for rear muffler replacements for these model years is at SpeedyCarParts.com who have the mufflers available as separate parts for only $96.20 each.
Filters Range Rover 4.0 / 4.6 /P38A
Air Filter:
The air filter setup for the 4.0/4.6 is different from the Classic; the genuine part number is ESR341, and the FRAM number is CA8009, Wix number 42272. Alex Schubow reports the genuine filter from the dealer cost him less than the aftermarket ones for the 4.0 engine! (I have found prices from aftermarket suppliers are generally about $12-15). The 1999 and later models with the Bosch intake system have a different-looking air cleaner housing, but it takes the same filter element. For those who wish to try the K&N re-usable filter system, the K&N part for all Range Rover models is the HP2004.
Fuel Filter:
Genuine: The genuine fuel filter is available from The Rover Connection for $28.
Generic: FRAM part number is GS3727 (Same as for the later Classics) and the Wix number is 33481. Atlantic British sells a generic filter for $21.95. A Bosch equivalent is available at the SpeedyCarParts.com (click on "Rover" parts) for $13.02. The FRAM filter is listed at ExpressAutoparts.com for $12.30. I found the FRAM one at partsamerica.com for only $11.99!
Oil Filter:
The Rover V8 is known for losing the prime on the oil pump so it is important to get a filter with an anti- drainback valve. The oil filter used on the 4.0/4.6 is the same as on earlier Range Rovers; FRAM lists the PH16 as a suitable substitute. I found this one at partsamerica.com for $4.49 (October 2004). Alex Schubow reports that Genuine Land Rover oil filters are made by Wix. Paul Supp looked it up on the Wix site and the part number is 51068. A few years ago, Alex bought various substitute oil filters at auto parts stores, finding that prices for Bosch were around $3-4, AC were around $3, Mobil-1 were around $5-6. Bruce Powell uses a PH8A instead due to a larger size in height thus holding a bit more oil which he feels might be better for cooling too. A great deal of information on different oil filters can be found at this link.
Pollen Filters:
For quite a while, genuine pollen filters (BTR8037) were less expensive than aftermarket replacements. Now they are both about $14 each from most mail order houses (2 required).
Transmission Filter Kits: Every 30,000 miles the transmission filter is supposed to be changed. (For details on this operation see the 4.0/4.6 transmission service page). The kit to do this, complete with new gasket and O-rings, can be obtained from aftermarket sources such as Atlantic British sells it for $59.95 and SpeedyCarParts.com (click on "Rover" parts) for $36.09. The lowest cost I have seen so far (October 2004) was at partsamerica.com where they list a generic substitute kit for $17.47!
Fuel Delivery System Range Rover 4.0 / 4.6 /P38A
Fuel Filler Cap:
Land Rover Part Number NTC5418: This is one part that is cheaper than the Classic equivalent! I was surprised to find it at Atlantic British for only $11.95. If you are willing to try generic parts (at your own risk -- I don't know if they have the correct air and cacuum venting -- let me know how they do!!) Stant lists the 11819, available from Kragen, Schucks, Checkers etc through partsamerica.com for $7.38. ExpressAutoparts.com lists it for $8.44, and an even lower cost Gates equivalent (#31612) for $6.34!! To find these, click on their "Cap (gas/rad/oil)" parts category.
Fuel Filter:
Genuine: The genuine fuel filter is available from The Rover Connection for $28.
Generic: FRAM part number is GS3727 (Same as for the later Classics). Atlantic British sells a gneric one for $21.95. A Bosch equivalent is available at the SpeedyCarParts.com (click on "Rover" parts) for $13.02. The FRAM filter is listed at ExpressAutoparts.com for $12.30.
Fuel Pump:
Model years 1995 thru 1997 use part number STC4344. The genuine Land Rover part now costs about $360. The best price I have found for a full "plug & play" replacement (April 2004) is $299 at British Pacific and from Atlantic British for $289, including the necessary ring seal for the top of the pump (a $12 item). You can also get the complete assembly minus the seal from SpeedyCarParts.com (click on "Rover" parts) for about $300 with free shipping, which may work better depending on shipping costs. Evan Amaya reports finding a generic equivalent -- the Airtex E3270 -- which worked perfectly for him and only cost him $100 at a local auto parts store. Like the generic replacements for the Classic, this is the pump and motor only, and has to be installed in the original mounting assembly. (See photos on 4.0/4.6 fuel pump replacement page). This pump was used on a number of GM cars. I found this pump at partsamerica.com for $96.99, and the same thing in the "Master" brand for only $74.99 (search for "E3270" on the partsamerica site).
1998 and later models use part number STC4345 which is more expensive -- the best price I have seen for the genuine part is $380 from The Rover Connection. However I was surprised to find it recently (October 2004) at SpeedyCarParts.com (click on "Rover" parts) for $295 with free shipping.
Fuel Pump Relay:
I found this for only $7.95 at Atlantic British
Fuel Injectors:
The fuel injectors on the 4.0/4.6 should be the same part as on the Classic; SpeedyCarParts.com (click on "Rover" parts) sells the genuine Lucas injectors for $102 each (free shipping), and Bosch replacements are available from Atlantic British for $99.95.
The lowest price I was able to find on a recent search (April 2004) at $599 for a set of 8 ($75 each) at Atlantic British.
Update June 2005: The lowest price I could find for individual injectors was $80 at British Pacific (part number ERR722, 95-98). However I recently discovered that Five 0 Fuel Injector Specialists have brand new warrantied OEM Bosch injectors for all RR models for $280 per set of 8 -- equivalent to about $35 each!! At these prices they do not sell them individually, just in sets. David Giller reports he got a set from them and they arrived in two days -- installing them completely cured his 1998 4.6 hard starting problem.
Fuel Tank Cap:
The genuine gas tank cap is available at The Rover Connection for $27; I found a replacement for this at SpeedyCarParts.com for $18.
Inertia Switch:
This turns the fuel system off in case of collisions. It is an expensive part, but I found a generic version manufactured by Standard at JCWhitney.com for $56.44 (Click on "Replacement Parts"). ExpressAutoparts.com has a similar unit to fit the Range Rover for $57.79.
EFI Parts:
See Fuel Injection System section below.
Fuel Injection (EFI) System
ECUs:
Car Electronic Services can supply rebuilt engine ECUs for the 4.0/4.6. RPI Engineering offers ECU upgrades, available in the US through East Coast Rovers. Kelly Minnick discovered that a company called Superchips Inc produces performance upgrade chips for vehicles previously considered "unchippable". They developed an enhanced chipset for the Range Rover 4.0SE which requires 2 chips instead of one (due to the 4 coil ignition system) and boosts output by 19 bhp and 30 ft-lb of torque. The Rover Connection also lists a Powerchip brand performance chip for about $490.
EFI Parts:
Richard Keys of ATP Electronic Developments Ltd reports having a huge range of remanufactured electronic fuel injection parts available for all Range Rovers.
Fuel Injectors:
The fuel injectors on the 4.0/4.6 should be the same part as on the Classic; SpeedyCarParts.com (click on "Rover" parts) sells the genuine Lucas injectors for $102 each (free shipping), and Bosch replacements are available from Atlantic British for $99.95.
The lowest price I was able to find on a recent search (April 2004) at $599 for a set of 8 ($75 each) at Atlantic British.
Update June 2005: The lowest price I could find for individual injectors was $80 at British Pacific (part number ERR722, 95-98). However I recently discovered that Five 0 Fuel Injector Specialists have brand new warrantied OEM Bosch injectors for all RR models for $280 per set of 8 -- equivalent to about $35 each!! At these prices they do not sell them individually, just in sets. David Giller reports he got a set from them and they arrived in two days -- installing them completely cured his 1998 4.6 hard starting problem.
Fuel Pressure Regulator:
Most aftermarket suppliers do not even list this part, however I found a Lucas brand one recently (October 2004) at SpeedyCarParts.com (click on "Rover" parts) for $136 with free shipping.
Idle Air Control Motor:
This item (ERR4352) is not a constant troublemaker on the 4.0/4.6 as it is on the Classic, but on the downside it has certainly been known to fail and is even more expensive than the Classic equivalent. It seems to be the same part for all models including the later Bosch engines. Lee Schierbaum had a problem with this unit on his 1996 4.0 and instead of the $200-plus genuine item he located a NAPA replacement part (Echlin #2-1856) for $52. The part also fits a Jeep. Another part number I have seen for this is AC-151. Matt LeFande (September 2004) found an even less expensive replacement at partsamerica.com -- a Borg Warner 21774 for $39.95! They also have a Niehoff Ignition 21774 that can substitute.
If you would rather use a regular Rover parts supplier so you know for sure the unit will fit and work according to spec, the best price I have seen for this part (October 2004) is $139 at British Pacific (part number ERR4352).
Mass Airflow Sensor:
The OEM part for the 95-98 models is over $600, but I found a generic replacement for this part at SpeedyCarParts.com for $398 with free shipping. In 1999 the part changed for the Bosch engine controls, and I found the MAF sensor for these models at SpeedyCarParts.com for only $290.
Oxygen Sensors:
The US spec 4.0/4.6 has 4 Oxygen Sensors(one ahead of and one behind each catalytic converter), so replacing them all can get expensive. NOTE: If you get an aftermarket replacement, make sure it is a full 4-wire version, not a "4 wire to 3 wire" version -- see below. One useful source for looking up the sensors specified for the 4.0/4.6 is the manufacturer's website, NGK -- at
www.ngk.com.
OEM "plug and play" replacements are available at The Rover Connection; the genuine O2 sensors for the 95-97 models (ERR1834) can be ordered from them for about $220 each, but they can supply aftermarket ones for $130. Sensors for the later models (AMR6244) are $180 from the same supplier. The lowest price I have seen for the OEM style plug and play sensor is $115 from automedicsupply.com (earlier model years); the lowest price I have found for the 1998 & up models is at Atlantic British which has OEM plug & play O2 sensors for $77.95 for the front ones (MHK100940) and $69.95 for the rear(MHK100930)!! (select their exhaust" category).
Michael Nix had the "Check Engine" light come on recently on his wife's 96 Range Rover. A trip to the dealer revealed confirmed that the engine had a slow oxygen sensor. Instead of paying the $275 from the dealer, he got one at a Nissan dealer for $90 (part number: 22690-85E10). He spliced the Range Rover connector on to the Nissan sensor and it fit perfectly. Three out of the four wire colors even matched up. I recently found this part by searching for its part number at SpeedyCarParts.com for $58.43!!
Alan Rawson delved more deeply into the O2 sensor problem on his 96 RR, adding substantially to our collective knowledge. He found the dealer price had dropped to $130. He found NAPA offers a similar item but with different connectors, their part # OS 778 (I recently looked it up and priced it at $81.99; it looks like the Nissan part mentioned above). Alan initially chose a Nissan part by NTK, which he found for $56 at a web company in southern CA.,
www.automedicsupply.com (their part # 250-2505). However, this replacement was a curious one with 4 wires at the connector reducing to 3 at the sensor. The vendor thought it would work fine, since the 4th wire is just data ground. All appeared to be OK at first, but Alan found that when the wires to one sensor were sheared off during an off-road trip the GEMS computer could not detect the problem (no light came on) and gas mileage went down the tubes. After further research, Alan found another part by NTK for $89.99 (current price $114.95 as of October 2003) which has the OEM connector (
www.automedicsupply.com part number 250-8004) listed for the 4.0, quoted to replace OEM #70399A-- that number was stamped on his old original ones!). The 4th wire provides data ground, and with the semiconductor circuits used in the GEMS computer it appears to be important to have this separate ground, so the computer can detect failure of an individual sensor through the ground circuit. Ron Beckett checked the NGK manufacturer's website at
www.ngksparkplugs.com and reports that their part number for the O2 sensor with the right plug for 95-98 models is 25017. Their UK site calls it a OTD3J-5C1, number of wires 4, connector style 57, lead length 521 mm. On Australian models a 3 wire unit is specified, OTD3G-3A1, with connector style 55.

1999 4.6 needs some work; fix or sell?
