There is company that has recently brought out a air filter for autos. The filter has been in use for years on Motor Cycles and has the lions share of this market. It is a foam filter , polyurethane , and this type of filter has been extreemly sucessful on dirt bikes as well as street. It is in direct compitition with K & N and independant lab tests show it to be superior filtering the air of dust and dirt. The Dyno tests show that it FLOWS AS MUCH AIR WHEN DIRTY as a paper or K & N will when they are NEW. K & N claim that they filter best when dirty , but don't breathe and flow air. I have no connection with this company and my only exposure to them has been in the past with dirt bikes . Now that they have come out with one for autos I thought I would pass on the info. With our cars getting up in years I have found that air filters for the '70--'72 air cleaner are not as available as they used to be. This is a reuseable , washable filter . Like the K & N is . The number for the filter is #70200 . I just thought I would pass on the information to all. Gary OK OK I dident want to get in trouble as an add. I was having a senior moment The company is True Flow !!

Thanks Gary. Are these sold only in Motorcycle shops or do they have a website that you know of? I'm happy with my K&N filter (the brochure I had claimed it cleaned better when dirty than new), but it's always nice to have a second source for items.

These are sold in auto parts stores. They have a web site trueflow.com there is another site unifilter.com/performance-facts.htm The secound co has only bike and truck applications. The testing of these filters is informative. I know that there is always someone wanting to build a better mousetrap , but I think that is worth looking into.
