My experience with the ordering process was great the selection process was easy and the shipment was made in a timely manner. I'm not so sure the actual filter will make as much difference in the driving experience as it has with our other vehicles. With our 2011 Fusion and 2006 Chrysler 300 there was a noticeable difference in performance and mileage, and with our 2005 Jeep Grand Cherokee there was a big difference in performance (plus it sounds great), where there doesn't seem to be any difference in performance on our 2014 VW Passat TDI SEL and the mileage actually seems to be a little less at highway speeds. The actual filter fit is different too, where it is literally 1/2 the depth of the factory filter.

This K&N air filter easy to install and you will notice the increase in performance just as advertised.

Replaced the filter with a K&N and noticed that my gas mileage has edged up a little in my GLI. It also seems to breathe a bit better during acceleration. I have K&N filters on all three of my vehicles and swear by them.

Long time user and the wife's drop in filter for her Passat did not disappoint. Much better performance for such a simple change. I love these air filters! One question. They seem to work forever.. How often should they be serviced?
