Customer Feedback

I am averaging more then 5 miles per gallon more on my 2014 chevrolet silverado 5.3 liter. My wife thought I was crazy, until she drove it and saw the savings herself. I will never use another filter again. K & N air filter is the best.

Fits perfectly in a 1966 Citroen 2CV (Type A53, 425cc engine)

Easy to install and noticeable improvement in sound and acceleration. I've installed K&N filters in all three of my Corvettes and in my 1996 Porsche Carrera 4S.
