Every 10,000 miles you have to replace your air filter at $20 a piece, after 25,000 miles you are saving money. I gained about 1 mpg over my stock filter in my Denali. I did a lot of highway driving before I installed it and always got 16.3 or less. My first trip which was over 300 miles I averaged 17.4 mpg, using the vehicles trip MPG meter. I fully believe in the product." —Brian S from Pullman, WA bought a K&N Air Filters for a 2009 Ford F-150, 6.0L V8.

"A replacement paper filter from the parts store costs $15. This aFe is 4x that but should last forever. I like the idea of not having to oil it too which adds to the cost.

I have no way of measuring that but I will have to take their word and it has to at least perform as good as stock." —David D from Gurnee, IL bought an aFe Pro-Dry S Air Filters for a 2009 Ford F-150, 4.6L V8.
"I have had this filter installed for a couple of weeks and haven't noticed any added performance or mpg increase.
