The restrictive stock intake manifold on your Mustang GT really holds it back from performing at its best, especially in high RPM ranges. Ford Racing created the Boss 302R intake manifold which easily drops right into place of your stock manifold and can get you a boost up to 50 extra horsepower. While this modification requires custom PCM tuning, we think it's well worth it. After you've shopped for a Boss Intake Manifold, take a look at our 2011-2014 Mustang Performance Packages and 5.0L V8 Axle-Back Exhaust Systems.
