I've been buying K&N filters for over 30 years and am very happy with the performance of my vehicle once I switched the filters out. Couldn't be happier with your products

Installed one of these filters in my wifes nissan maxima. Now, when she steps on the gas, the car zooms. When we took the on ramp to the freeway And accelerated 2 seconds faster than It took with the factory air filter , the car just flies It is now faster than it was when we bought it new 10 years ago. I am so glad I bought your k and n filter, it is a fantastic product.
