Amazing filter.

2011 Range Rover Sport Supercharged The replacement filters were noticeable immediately. It takes less throttle to get the acceleration you want, fuel economy went up 2-3 miles per gallon and my exhaust definitely has a deeper/throaty sound. Overall the drive ability was improved, power feels like 15-18hp increase, and fuel usage had instant improvement. I have K&N's in my 2011 VW Touareg TDI and 2014 Audi S6same experience with all my vehicles!!!!!

Massive difference to my Range Rover Sport. Pulls better, gear changes are smoother. Finally the big V8 can breathe. Very happy.
