I went from a Fram Tough Guard air filter to this thinking it would improve my overall horsepower and MPG and boy has it ever! Within the first month my hp has increased by at least 5hp and I'm getting almost 18 mpg! Which is fairly decent for a 5.0 v8 engine. I would recommend this filter to those wanting to get the most out of their ford 1995 F150 pickup!

Love it! Old truck never ran and sounded so good. Amazing what more air will do for a motor.

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