"The engine sound nice it has a quicker pick up but I haven't seen a MPG increase. Over all it's a great system." —Joseph J from Jeanerette, LA bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 Ford Expedition, 4.6L V8.

"The spacer was simple to install. the instructions could provide a simple drawing for the very inexperienced. It does not whistle as I drive (I read this from another review). I have not noticed a significant amount of power. The on board computer averages fuel consumption while on the freeway cursing at 1999 RPM's in overdrive the average went from 17 MPG to 19 MPG, ( it could have been great tail wind). I have only had it installed a week now and have driven 300 miles.. So far it seems to be a good product.
