This filter was a big improvement over the paper one. My fuel mileage went up slightly. My 2015 Cayenne Diesel had the emissions fix done and the car ran rougher after that; this filter has helped the engine run better. Most power has been restored now.

Installed this filter in a new 2017 VW Touareg, 3.6 liter. I have used K&N filters in all of my vehicles and I am sure I will experience the same satiisfaction with this one.
