Spark plugs: Bosch fusions/+4 - Champions?

[Jupiter Rover]

So what are the bst plugs for a disco II.. i saw a add in petersons 4x4 about the Fusion plugs. anyone hear anything about them?

also, what do you guys like best with magnecore wires. ?

Just get some stock ones- there are a couple people who swear they got 50hp and 35 more MPG because of plugs, but the vast majority of the time the goofy aftermarket plugs just cause problems. No reason to tempt fate.

Steve is right. Just get some stock Champions and be done with it. Chris is on this board now I am sure he can shed some light into the Bosch "BS". My 0.02 cents!

They DONT suck lmao. looking into NGK and fusions now.. champions just seem a bit average.

If Bosch sucked as you put it, they wouldn't be the company they are, who else offers a money back warranty if you are not happy with them, no one. Yjey are the same price as the factory plug and won't give you great bursts of horse power put they will inhance the low end torque.
And yes for about $3 apeice more you can get the new Fusions.
If the plugs didn't work well, I doubt BMW, Mercedes and many of the high end manufactures would want to rish have a poor running engine.

i just said what i researched. i dont know. never used them. im not Against them At all, im either getting the fusions or NGK irridiums.. been researching for a while .. just ALOT of people say they suck.. prolly because they didnt upgrade there wires..

They routinely cause problems on DII's. Anyone who has worked in a shop that does L.R.'s would have seen it before- the evidence has been in the many many posts all over where people had problems.
Bosch plugs don't suck in general- they are good. They are NOT a good match for the DII though. The original ones always work, Bosch don't always work on these trucks. Why bother?

[Jupiter Rover]

yeah, heard Alot of good news about the NGK product. im going to hit up pep boys and see if they carry them. NGK seems like a safer road than bosch.


thanks for all your replies ;!

I would stay away from Champion plugs, I have always had nothing but problems with them.

[Muddy Oval]

LOL! Champions are what comes in the NAS Discos. Fitting anything else invites problems, but the original plugs don't have problems. Why avoid them?
Good grief, people... why don't we just re-engineer the whole truck and second guess everything? Something SO easy is made difficult because people just want to change stuff for the sake of changing it.

The spark plug debate along with the K&N filter debate will go on for ever. Having used Champion plugs as well as NGK's, I'd have to say that the NGK plug is superior. NGK BP5ES would be just perfect for a standard Land Rover D1 or D2.

X2! No issues yet with the Champions and ran on the 1998, 2001, and 2002 D1 and D2.

Steve,
I agree with you and your frustration over the issue of plugs in Rovers, we have been having the same issue flair up many times over the last few years with no real conformation and testing around anyones answer, just lots of options or 2 cents worth.
A little over 3 years ago, I needed to change out my plugs and read some of the same stuff even back then so I went a little different direction then most, I took my truck to a friends shop with 2 sets of plugs in hand, some factory Champions and a set of Plus 4's. My idea was to put in half Champion and have Plus 4's in in 2 different tests, one runn all Plus 4's on one bank and Champions on the other. The othe variation was to run on Plus 4 next to one Champion all the way thru the firing order. We then hooked a failrly new SEA scope from Allen test products into the OBD2 access port and pulled up a scope showing each cylinder at the same time, how it was firing and the total % each plug was contriputing to the engines performance.
End result the Plus 4's, being fired off my newly install Magnaco wires did out perform the factory built Champions, not by a huge % but by enough that it convience me to go Bosch. I have run them ever since, even in my old high mileage Mercedes and haven't looked back.
Al that being said, with all the BS going around, most peoples options are unfounded and can't be verified. I am least and at least able to say for sure after a couple hours in front of a scope.
So as you and I have both agreed to in the past still holds for me, we may have to agree to disagree, but for all the others out there, I wish people would really research their options before posting them cause there are many people on this site that are looking for well founded options not hear say.
By the way, I still have that set of Champions which I never installed, kind of an old reminder.
Take care,
Mike

way to put that argument to bed, Mike!
I should be getting my Boschs tomorrow! is $6 ea an ok price?

I got Magnecor 8mm wires for $69 out of Pennsylvania (shipping to RI was $8)

What you're missing is that many people have had problems when fitting aftermarket plugs. Talk to a delaer tech (Chris St.L for one) or talk to the guys in our shop and you'll see without a doubt that there is a definate trend of problems fitting those plugs. Maybe they work for you, but the vast majority of others are not having such luck. The garbage can in many shops are lined with attempts to use all these magical plugs.
