Review part 33-2446

I am very familiar with the fine products and performance value K&N delivers. I've used these incredible filters on all of my vehicles (two Jeep, SRT, 8 SUVs and my current 2014 Range Rover Sport 5.0L Supercharged) I can feel the difference.

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!!!!!

Fairly easy installation process. The product arrived quickly and packaged well. No noticible change in MPG, but throttle response does seem to be improved.
