Love it! Old truck never ran and sounded so good. Amazing what more air will do for a motor.
Jake Myers, Nebraska
Installed this product on my 1991 Ford F-150 and what a difference it has made. Definitely gave it more power and about 3-5 mpg better. This was a want for this truck, now a NEED for my other vehicles.

Proper fit and function. My fifth filter purchase from K&N filters.
