K&N Replacement Air Filter
  • Designed to Increase Power
  • Million Mile Limited Warranty
Robert Burns, Virginia Beach, Virginia
Installed in a 1999 Jeep Grand Cherokee. A perfect fit replacement for the old throw-away filter. The Jeep air filter box is easier to open than the one on my Mazda Miata. The Mazda was the first K&N filter I bought and it was great - real performance improvement. The Jeep is no sports car and with only 4.0 L and a moderately heavy SUV, I need as much performance as I can get. A good investment for cars I intend to keep a long time.

I had an air filter in my Dodge Ram and I swear I got 2 more miles per gallon of diesel. I will always have one in my car. I love them. THANK YOU -Richard Lloyd

I purchased this replacement air filter for my 2015 Nissan Frontier. It was a snap to replace the OEM air filter and though I have not noticed a difference yet, I am confident it will improve the engine responsiveness and overall performance of the vehicle. I have changed to K&N on all of my vehicles and motorcycle.
