I'm glad this kit has 2 filters, one for each side of the engine, so that I don't have to buy two separate ones. The kit includes two different K&N stickers, so I can put one on each intake.

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

Bought for my 2013 Range Rover Sport Supercharged, been about a month now. Noticeable improvement in the snappiness off the line. Picked up about 2 mpg at highway cruising, 79-89 mph, nothing helps around town, too much fun to get on it.
