"This letter is written to you and all the staff there at K&N to thank you for your courteous help in building the cartridge to fit the canister for the air filter on my motorhome which has the 300 hp Cummins engine. We had an opportunity to drive the motorhome during the Thanks-Giving holidays. The trip was approximately 400 miles. The first thing I noticed was the increased performance of the engine. The coach performed better than it ever was, and it was purchased new in March of [1993]. The next thing that caught my eye was the absence of black exhaust smoke upon heavy acceleration. I wish I had checked the mileage, but I do know that the mpg increased dramatically. The next trip was also made towing our 1993 Jeep Grand Cherokee, which is no lightweight. Last week, I immediately ordered a K&N air filter cartridge for both the Jeep Cherokee and our new 1993 GMC truck. That should tell you I am a believer in K&N filters."

Obviously easy to install as it simply replaces the old filter. I saw an increase of 1 mile per gallon - which for my 8.1 liter GMC truck was nearly a 10% boost in MPG performance. I've asked my wife for the full K&N cone shaped free air flow filter conversion kit for Christmas. If this simple replacement filter helps my MPG this much, the conversion kit to the cone shaped filter should be great. This is the second time I've converted a vehcile to K&N and I've been totally pleased each time.

I put this on my stock OEM housing with my K&N Air flter replacement for OEM Filter. Works great!!!I Improvised and just drilled a hole on my Stock OEM Filter Housing and adapted this. Used a similar set up years ago in trash trucks in Dad's Trash Buisness on Mack,Diamond Reo,GMC Generals,and Autocar Heavy Duty trucks!!!
