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.

My new K&N Air filter has made a difference in my car's response and power. It is worth it. The K&N store was very prompt in the order and correcting a mistaken part sent that didn't fit my car (probably my own fault) They made an order correction easy by sending a prepaid shipping label to return the part.
