"At first I noticed a slight increase in power on take off. I did not expect to actually notice any power increase like the add says but I did. I could hear the intake when accelerating, it sounded like the engine was getting more air. So far I really like the product and I am pleased to finally purchase a product that does what it says it will do. I plan to check gas mileage next, hope to be suprised there also.
I am planning to buy another one for my wifes' car." —Dan B from Wichita, KS bought a K&N Air Filters for a 2009 Ford Mustang, 2.0L 4-cyl. engine.
