Simply the best. Noticed immediate increase in performance. Do NOT put off purchasing one of these filters because of the cost, pays for itself after 3 regular filters -WRX driver

Jared wright, Colorado
My air filter is great. I've got it on my stock class car for rallycross in Colorado and the only thing I would want to do is maybe rep K&M as a sponsor or something. Maybe some shirts I could wear at races and on my youtube channel that I just started.
