I first purchased the K&N Air Filter System. I noticed no difference in power and gas mileage. My vehicle sounded worse than before. Then I purchased the Air Filter Wrap. Noticed that my vehicle was running a little bit better. They should highly recommend the Wrap when purchasing the Air Filter System.

Switch out stock filter for the aFe pro-dry S air filters in my 370z. After two months of use I have notices a 1.1 more MPG so I am very happy with that. I also feel like the car shifts smoother through the gears.
