A very good product and service.
Dave Fuss, Truth Or Consequences, New Mexico
Excellent air filter as always. Noticeable difference in fuel mileage of 1 I 1.2 mile per gallon after installation. I’m a hunting guide on a lot of dusty roads here in New Mexico and I know I can trust my K&N filter to keep my engine protected. Filter is easy to clean when it gets dirty. Well worth the money.

I am disappointed with this filter, I haven't had any increase in fuel mileage at all. To be fair it has only been one tank full so far. Maybe it will help over time.
