Improved throttle response. Noticeable horsepower boost. Nice sound not too loud. Can't verify MPG as my foot has been in it more. Relatively easy instal for mechanicially inclined. Factory throttle body cover will not fit at reinstallation due to placement of bypass and breather hose connections on air intake tube. Minor detail that can be fixed by longer hoses and reroutes. Overall happy with it.

Awesome product from AFE, they truly know how to make a quality product. Easy installation, great looking product that literally drops right in. Fuel mileage increase of about 3%. And a 5.4 liter that can breath.
