Russ Maxson, Budd Lake, New Jersey
Have been a K&N user for 40 years and use their products in both my street cars and my race cars. Simple, guaranteed to fit right and economical since they are cleanable and resuable. Can always count on them for some extra fuel milage gains too once the ECU has time to update itself.
George Scannelli, West Caldwell, New Jersey
Great. More acceleration. Love them.
Mark Oltman, Colorado
As usual, excellent product. Immediate difference noted in performance. Will always be a K&N customer!
