Ram AIR MAY be Better....
I have a Ram Air filter, and it uses a tripple foam media.. its pretty damn good, plus you don't have to worry about desroying it when you clean it..
Its true the the oil does tend to get in there, but when I am taking off the filter to clean it i take a Qtip and alcohol and clean the wire.. it takes 3 min and is a no brainer.. you have to clean it now and again anyway..
they have them cheap on ebay.. I have one up for sale on the classifieds link on this site..
Here is the pitch that sold me..
One (1) RamFX direct replacement high performance air filter that will fit the last year of the classic Range Rover and the Series 1 Discovery models. Check the application list below to confirm your model and year.
The filter, part number 10.1174, reflects leading edge filtration design that has been proven at all levels of motorsports from World Rally to Indy, and from Touring car to Baja.
It is just one of a range of high performance direct replacement Air Filters and Air Pipe kits that FXteknology is selling on eBay as part of our efforts to re-introduce RamFX products, formerly sold under the RamAir brand name, back to the performance and motorsport markets.
The Story On RamFX Filters -
The RamFX direct replacement air filter is the best dirty filter in the world. The statement sounds kind of funny, but what other air filter manufacturers do not tell you is that they base their filtration claims and air flow ratings on a brand new, prefectly clean filter.
The problem is, you really never run a brand new, prefectly clean filter on your vehicle. The minute you turn the key after swapping out the old one, the filter begins filling up with dust and dirt that starts restricting airflow.
The teknology used in a RamFX air filter was developed to deal with the fact that your vehicle spends its entire life running with a dirty air filter. It is just matter of degree, of how dirty. Our filter is made to flow more air when it has ten or twenty thousand miles on it, than a brand new filter from the competition.
But why is a RamFX filter the best , dirty or otherwise? It is our proprietary air filtration technology. We call it polymer impregnated volume media or PIVM and it is the next teknology in air filters and air induction systems.
Paper filters rely on 'surface' technology where dirt is trapped on the surface of the filter element - a bigger particle trapped by a smaller hole. Oil impregnated cotton gauze filters rely on what its originator calls 'depth loading' - oil coated fibers trap dirt throughout the depth or thickness of the cotton gauze.
But the depth of a cotton gauze filter is really no more than the thickness of a t-shirt. Its performance really just mimics the older 'surface' technology of paper elements. During extreme use or long service, either style of filter is overcome by surface loading, reducing airflow. In fact, the originator of the cotton gauze filter admits that airflow through their filter is reduced 40 percent when it is dirty.
For either technology, ultimate filtering capability is then directly related to surface area. That is why they pleat the filter. But no conventional filter can hope to duplicate the total surface area of a RamFX air filter. Our unique reticulated Aerofoam material has millions of air passages coated with a sticky polymer.
The airborne containments adhere to the walls of the pathways as they wind their way through the 25mm thick, three stage volume construction. Even the smallest particulates, measured in microns, are captured progressively through the entire structure while avoiding the surface loading of conventional filters.
This breakthrough air filtration teknology of a RamFX filter, or Series 10 as it is also called, gives your vehicle the best air filtration possible and a noticeable increase in power due to its enhanced air flow over a longer service life. Horsepower improvements vary depending on the vehicle make, model and year, but a two to eight horsepower increase is common.
It is a lifetime investment for your car and the last filter you will ever have to buy. Conservatively, over 25,000 miles service intervals can be expected before it is necessary to clean and then renew the filter with the available Cleaning Kit.
After every restoration, regardless of the number of times it has been cleaned, a RamFX Series 10 filter will once again perform to its original design capability. That means maximum filtration efficiency, high dust holding capability, low airflow restriction and long service life, while improving engine power. Would you expect less from the best dirty filter in the world?
• Improved engine performance due to enhanced airflow over a longer service life.
• Traps up to 4 times more dirt than paper filters and up to 2 times more than cotton-gauze.
• Filter is reusable, just clean with PRC solvent and re-treat with DRP treatment.
• Soft, flexible seal conforms to airbox to prevent dirt from getting around filter.
• Achieves filtration efficiency of up to 99 percent.
• Carries a Limited Lifetime warranty.
• World patents pending.
• Retails for $40 to $44 dollars.
