Review on Airaid Cold Air Intake System for Ford Mustang 2011-2014: Boosted Horsepower, Premium Filtration - AIR-451-265 by Josh Allred

What a thrill! The device was installed in about an hour, all the instructions were there. The only tense moment was attaching the knot to the throttle neck, but it's just a matter of patience. At first the engine sounded weird under full throttle, but as the on board computer got used to more air the sound got awesome! As a layman, the performance gain is hard to gauge, but I'm guessing between 11 and 13.mpg up an average of 2mpg. . .it is NOT possible with a permanently heavy leg! Worth the price. . .now to the axle silencer kit! Incidentally, this was installed on a 3.7-liter V-6 Mustang '12.
