I wanted a K&N replacement filter for the 6.0, but the only one I could find was the entire intake kit. Now I know why. the stock intake is very restrictive. I installed the K&N Intake kit and am very impressed. The installation was very easy, the instructions excellent. Everything was included and fit correctly. The performance of the truck is impressive. There is a noticeable increase in power while towing heavy, and the gas mileage improved by almost 12% while towing. Excellent!
