Jorge L Morales Scharon, San Antonio, Texas
Very easy to install. Immediately delivered performance as per specifications I did not receive any notable efficiency in gas savings.I own a 6.2 L GMC engine. Would recommend this product to others.

Product works as advertised. I didn't get a noticeable increase in power, but my throttle response and idle is better, and my engine revs faster and higher
William T Whalen, Madison, Wisconsin
This is my 2nd vehicle now with a K&N air filter. This vehicle has noticeable more power on start from a stop and I have calculated a 3.1 MPG increase with no other maintenance performed on this vehicle. I received a recommendation for a K&N air filter from a friend and have also continued that practice with my friends and family. Great investment for any vehicle of any year.

Delivery was quick, can't fault the product. If you need a new filter why not get one that will last and preform better.
