Fast, free shipping. Easy to install. Easy to clean. I put these filters in every car I buy.

Unlike many people, I keep my vehicle for an average of ten years. The K&N filter I selected for my 2013 Chevy Equinox fit perfectly and will save me in maintenance costs over the life of the car.

We were thinking of ordering a K&N air filter for our new vehicle when you sent me an email with a $25.00 coupon. It was an easy decision to make. I ordered online and you shipped it to us right away. It was best to order through you, as you had a different style for our vehicle than (Brand Replacement). You, of course, had the correct one. Plus, your price was the best as well. We now have a K&N air filter in all of our cars. Thanks

Bought as a replacement because of past experience with K&N. I put it in brand new vehicle. Fit is perfect, like always.

I'm sorry, but I couldn't tell anything much about it. Waiting and checking around for some type of tune.
