Michael Daniel, Bon Air, Virginia
I have one of these filters for all three of my vehicles. You can tell the difference in the power after installing these filters.
Dominic Tran, Ohio
I bought your KN air filter (33-2340) for my 2009 Ford Fusion V6 and must say have noticed an increase in power, especially at mid-range RPM. I drive over 45 miles each way to work everyday and have noticed just a slight increase in fuel efficiency as well. All in all, this product does what it says it will do and I am a very happy with it. Its a product that will eventually pay for itself and I will install a KN filter in every vehicle I will own.  
Damian Trotti, Lithia Florida
The filter did everything I needed it to. Very easy to instal and have not have any issues with it since I installed it. It seemed to have provided my vehicle with a little more horse power. Will continue to get my business.
