Product Reviews      Review part 66-3150

 I have owned my 86 Olds 442 since I was 15. This June I turn 26 and the car has always had a KN air filter. The same one I put in it when I first bought it. Since I always used the KN Xtreme filter top on my Late model why not use it in the Olds. They didn't make one at the time but since then KN has produced a filter top that fits GM standard air boxes. KN has saved this Olds close to 18,000 gal. of gas when added all up over the last couple of years. Thanks to all the engineers at KN for top of the line filters. The horsepower in my racecars is 2nd to none thanks to the KN crew.
