K&N Replacement Air Filter

Bought it for a 2013 Volkswagen Passat 2.5L 5cyl. Not only did it make my car sound SOOOO much better, but it increased the power significantly. Also, I drive a little hard and I use to get about 8-12 mpg in the Brooklyn city. Now my average is 16.5 after driving it really hard. This is the best thing I ever bought for my car, and it only cost me about $50. Definitely reccomend everyone to put this in their car, not only for the power and sound, but for the gas savings. This filter will pay itself off just in gas money. Definitely putting this in all my cars!!!
