Jason Bryson, Westminster, South Carolina
One of the best upgrades I have ever done to my truck I can really tell a difference and the added benefit of not having to buy a $70 paper filter every time I change my oil is great and the K&N filter will pay for itself in less than a year Don’t hesitate any longer buy a K&N filter you won’t regret it The only regret I have is I didn’t purchase it sooner.

Excellent air filter; this is the second I've bought my first truck really improved it's performance so I got this one for my second truck. The service K&N provides is second to none, from the online purchase to the delivery of my filter I got the best possible service.

From the purchase procedure to the delivery of my filter the K&N store was very professional. The filter is performing very well. I gained pulling power and 0.6mpg . Can't beat that!
