The 5.0L V8 under the hood of your 2011 to 2014 Mustang is a pretty darn powerful motor straight from the factory. That being said, some of the stock components are restrictive and hold your Mustang back from reaching its true potential. One way to instantly unleash 20 to 40 more horsepower is to replace your factory air intake system with a cold air intake. It's one of the least expensive and easiest ways to increase the volume of air flowing into your engine at lower temperatures to get you a more explosive air/fuel mixture and, ultimately, more power. After you've picked out a cold air intake, take a look at our 2011-14 Mustang GT/ V6 throttle bodies and 5.0L Mustang Exhaust Systems.
