K&N 33-2455 Air Filter Product Reviews

Monday, March 7, 2016 - Part 33-2455
Four new cars in the last ten years and everyone has been fitted with the proper K&N air filter. Performance improvement was achieved in each car and each person who purchased my cars thanked me for taking care of my car and its engine. I recently purchased a new Lexus 450h and checked with and received confirmation from 3 Lexus mechanics that replacing the factory air filter with a K&N was the best possible move to insure long lasting performance.

I have used your filters for 20 years. This is just as expected. The engine runs smoother than with the OEM filter and delivers at least 1 mpg improvement. Unstop the nose and it runs better!!

Excellent. After installed, improved the engine response and more smooth during gear shift.
