K&N heavy-duty wrench-off oil filters have a one inch nut making removal easier. The thicker canister increases burst strength while protecting against pulsation fatigue. The micro-glass media has very good cold flow characteristics while providing excellent capacity and efficiency. These oil filters have a premium HBNR base gasket for sealing, a silicone anti-drain back valve and a dichromate plated backing plate for corrosion protection. This heavy-duty oil filter was specially designed for a high compression turbo diesel engine's tight tolerances.

I love your guys products! I just put a FIPK generation 2 cold air intake (part # 57-2541) on my 2000 Ford F-150 XLT 4x4 7700 with a 5.4 liter. It adds so much! It sounds like a different engine! It has such a sweet growl to it. It even makes the truck sound like it has an exhaust system on it. I was extremely surprised by the added power to it aswell. But, the added fuel mileage is a LIE! I cant keep my foot out of it! Come on K&N, how do expect people to get better gas mileage when we install your incredible products on our vehicles? I will definetely come back to your products as long as I own a vehicle. Thanks again!

Piece of cake to install and like the K&N filter I put in my 2010 Mustang I expect the filter to be worth the initial investment

I recently experienced a failure in a component of my 57-2541 Cold Air Kit after 100,000 trouble free, fuel saving miles. The problem was easily diagnosed and repaired by me at home. I contacted Elzabeth Taylor in Customer Service who was extremely helpful and very understanding in regards to my situation. She instantly shipped me a the part to replace the part that I field fixed in my driveway. She requested that I take some photos and send them to her so that Research and Developement could take a look and make any adjustments if necessary. I was delighted to comply and sent them back to her later that evening. I have K&N Cold Air Kits in my 1999 Ford F-150 and my son's 2013 Chevy Sonic 1.4 Turbo. I have an air filter in my wife's 2012 Dodge Caravan. Your products have served us well and delivered the performance figures that you quoted. Actually, I got better than quoted performance on my 1999 F-150. I averaged over 1.5 mpg increase after the intallation. I will be purchasing a Chevy Silverado with a Duramax Diesel engine very soon. I am anxious to see what we can do with K&N products at that time. Keep up the good work and the great customer focused service.
