AMAZING!!! WOW, what a difference the K&N replacement filter makes for my 2010 VW CC V6. It really pulls hard from all rpm ranges. In fact, I'd say it adds 10-15+ hp without question. Thanks!!! Well worth the money.. highly recommended!

Bought for my latest car RS3 but not the 1st K&N. I have used them in a few of my motors, plus motorbikes. Always found them to be good filters along with the extra performance gained. Always a must, would certainly recommend.

Product arrived promptly as was exactly as described. Installation was easy and MUCH less expensive compared to the dealership prices. We are very pleased.
