"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."

I just bought a new 2014 GMC Terrain and I did what I've done with the last eight new vehicles I've purchased I replaced the original factory air filter with a K&N filter. In every case, I've seen an improvement in fuel economy and an increase in horsepower. What's not to like about that?!

Great product and my 2009 GMC Sierra 1500 sounds great, faster throttle response and looks great under the hood. It took a few hours to install and easy to work with, minor drilling but over all easy to install for someone that doesn't mind getting their hands dirty. Highly recommended.
