"This was bought to help improve fuel mpg. Installion was pretty easy. I quickly noticed the power increase (between 3500 and 5000 rpm). After 5 tanks of fuel I can say that I am getting about .8 to 1 mpg better without babying the truck. I just ordered another unit for my 05 chevy Z71." —Thomas B from Prairieville, LA bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2005 Mercury Mariner.
