Lewis, Pflugerville, Texas
I've had K&N in all my cars for the past 20 years. The response after install is always noticeable whether on my C5 Vette, Honda van, wife's Buick or my 49 Ford w/LS3 engine. My biggest problem has been my wife has gon in for oil changes and the dummies do not read the notice and replace my K&N with paper. Keep up improving em.
