In the two tanks of fuel used since installing this air filter, we travel an additional 40-50 miles on a tank. Since this car is driven by my spouse, I personally haven't checked the mileage, but it is definitely better. Acceleration is much better also.

A great up grade, really easy to put in the car. A noticeable performance improvement with a free'r revving engine. With a hint of induction whine as well; a big thumbs up.

The performance of the vehicle was markedly better after installing the air filer so much that I was truly amazed. The engine can breath a lot better and the gas mileage has improved. I really like the idea of just cleaning the filter instead of replaceing it every so often too. It's really a great product. Thank you so much, I am spreading the word.
