Wendell Putnam, Colorado Springs, Colorado
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.
