"Great filters. I purchased one for our 97 toyota since the disposable was only 10 less than the washable. Since the car is not really a high performance car, I have not really noticed any difference in hp or mpg. In our other car a 08 Ford Edge, it sounds better and the mpg has gone up by about 2 per gallon. We are really happy with the purchase. I am buying a new car soon and purchasing a aFe Pro-Dry will be my first add on." —Quinton H from Orem, UT bought an aFe Pro-Dry S Air Filters for a 2006 Audi A4.
