I have always used K&N products for one reason. They work great. Always have. The air filter is the best I've ever used. I didn't think it would be as good as it is. My gas mileage is the best I've ever seen on both cars. The engine runs better and cleaner.

Been using k&n filters since the '70s. Nothing better, used them in motorcycles, street cars and race cars and have never been disappointed. Thanks for making a quality product and I will continue to use them in each vehicle I acquire.
