Title: Don't believe the hype!!
Product review: All I can say is that I fell into the mpg scheme. I own a 2006 Dodge 2500 diesel and it actually hurt my fuel mileage 1 mpg. My cousin has a 2006 Powerstroke and he put on a K&N and he also lost 1 mpg. The only thing the AFE did for my pickup was make the cab noise almost unbearable. Buyer beware!!
