K&N HP-8021 Oil Filter

Performance Products > Oil Filter
  • High performance design for outstanding filtration
  • Allows for high oil flow rates
  • Easy removal by using attached 1 inch nut
  • Ideal for high compression turbo diesel engines
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.

Customer Feedback

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!

I put a K&N in my 2004 Ford F150 FX4 right after I bought it. Nothing but great satisfaction with it. Averaged 22-24 mpg on the road. Not too shabby for a 4x4 with a 5.4ltr V8. The end of March, this year, I downsized to a 2016 Subaru Forester. Ordered a K&N the same day. Arrived in perfect condition and the car runs great. Have already noticed a pick up in power and better mpg than the factory states. I have nothing but great things to say about your product. Keep up the great work.

The replacement K&N air filter has noticeably improved the throttle response on our Ford Transit Connect.
