Online order was easy, arrived quickly. Superior filter, noticed almost right away an increase in acceleration. Looks also that there is a noticeable improvement in fuel economy. Quality product, looking forward to trying more K&N products.

Over the past 25+ years I have used K&N filters on all my cars. I find them to be an excellent way to properly maintain a vehicle air filtration system.
