Tim Lowell, California
I have K&N air filters in all of my vehicles. Just bought a GMC Sierra 2500 hHD. Put the K&N in before the odometer turned 1000 miles. The filters are just that good.
Kai Wagenfuehrer, California
Great product. Perfect fit, as expected. I have used K&N filters in all my cars, BMW's, Audi's and Chevy trucks, and will continue to do so.

I've noticed an immediate increase in horsepower and performance.
