I waited until my F250 6.0 diesel went out of warranty and then installed the K&N kit. I just completed a 2100 mile trip towing a 30' travel trailer. Same route as last year @ 9.6 mpg. This year got 10.4 mpg. The power difference without the trailer is very noticeable. Installation was easy and clean.
