Easy install, slight fuel economy reduction of approx 2mpg, but whoa.... did these filters fill in the blanks on power smoother acceleration! Exactly what I expected, and at least another 20hp.

Was shocked to see how black my filters were taking my car to dealership...Thanks K&N..Charge for multi check of vehicle? Not any more ..will just check myself..
G Hardy, Valdosta, Georgia
Super easy to install, perfect fit, and quality second to none. I've been using K&N filters in all my vehicles for several years and they are everything as promised. I will continue to replace my stock filters with K&N products in the future as well. Best product you can buy for the money.
