I am very proud of my New K&N Filter. It seems as if I am getting better gas mileage. I am going to buy one for my other vehicle now. Thanks K&N.

Arrived quickly and well packaged. Item was well made and fitted nicely. Quality product compared to oem part.

Great product. My fuel pump was being over worked by my old fuel pump. I could stand next to my truck and hear a loud whine. After I took it off and put this K&N fuel filter on, except for the system pressuring itself, you can't hear the pump.
