Customer Feedback


Best filters ever. Run them in all my vehicles including my Harley Davidson Motorcycle. Saved a ton of $$$ too by not having to purchase replacement paper filters every time.
Bill Sleeper, Altadena, California
All of my vehicles including my Harley Davidson have K&N Filters installed. They perform without equal.
Robert W.Garcia Sr., Paradise, Texas
I have used K&N products for several years as a ship's engineer. I am now retired and still own the 1988 Harley Davidson FLST I bought new in '87. I also am still using one of the first Screamin Eagle CV carbs. No one makes the correct air filter, so I went back home to K&N for a universal filter that I knew would not only deliver the air flow necessary but would look good as well.
