Gain Serious HP and TQ. Bolt on up to 61 RWHP and 43 ft.-lbs. of torque to your 2011-2014 5.0 GT Mustang with a Ford Performance BOSS 302 Manifold. We dyno-tested this manifold in-house on our stock 2011 GT with nothing more than a JLT Cold Air Intake, so you can be confident you'll see some real performance gains from this manifold. This manifold is the perfect starting point for your list of power mods, especially if you plan on going forced induction. This is the same Original Intake Manifold that is found on 2012-2013 Mustang BOSS 302, Ford Performance BOSS 302S and BOSS 302R Race Cars.
More Air for More Top End Power. Your GT's stock intake manifold is designed to perform well at the low end, but it chokes off airflow at the top. This Ford Performance BOSS 302 "runner in the box" Intake Manifold features a short runner design for optimum flow at higher rpm's. This Manifold is ideal for peak engine power and sets the stage for future power mods.
Ready for Forced Induction. Tested for up to 2 bars of pressure, this BOSS 302 Intake Manifold is perfect for your upgraded heads, supercharger, and or cam'ed 4 valve motor. With this type of pressure rating, it can handle the increased air flow and deliver consistent power time and time again.
Calibration Required. Because the BOSS 302 Intake Manifold provides additional power through a different intake design (compared to the stock GT), reprograming of the vehicles computer (ECU) is required for operation. By reprogramming your Mustang's ECU, you will be able to realize the full power potential that this Intake Manifold has to offer.
Race-Quality Construction. Made of a high tech, lightweight composite and finished in stealth black, this manifold lives up to the BOSS 302 name, helping your Pony breathe better while improving under-hood appearance.
Bolt-on Installation. The BOSS 302 Intake Manifold was designed to bolt directly onto the heads of your 5.0L Coyote engine. No custom machining or fabrication is necessary for installation. This Manifold is compatible with your GT's stock fuel rails making for an easy swap.
Additional Hardware. If you plan to run your new Ford Performance BOSS 302 Intake Manifold with your GT's stock air box or an aftermarket Cold Air Intake, you will need to purchase the
BOSS 302 Intake Manifold Installation Kit which includes all the additional parts necessary for proper installation. Please see options listed above.
BOSS 302 Strut Tower Brace. Seeing that stock and aftermarket strut tower braces designed for the GT will
not clear the BOSS Manifold, it's recommended to upgrade to a genuine BOSS strut tower brace. A strut tower brace will help reduce unwanted suspension flex while greatly improving the handling of your Coyote powered GT. Please see options listed above.
Not CARB Certified. This Ford Performance BOSS 302 Intake Manifold is not CARB certified, therefore it is not legal for use in California or any other state adopting California emission standards when installed on a GT model. Not legal for use on pollution controlled motor vehicles; intended for off road use only.
Application. This Ford Performance BOSS 302 Intake Manifold is designed to be a direct fit service replacement for the 2012-2013 BOSS 302 Mustangs, but can also be installed on 2011-2014 GT Mustangs equipped with the Coyote 5.0L 4-Valve Engine. Intake gaskets are included.
Technical Note. When installing this Intake Manifold on a GT, some aftermarket Cold Air Intakes may require modification to the coupler or inlet tube for proper fitment. JLT and C&L Brand Cold Air Intakes will bolt-on with no additional modifications. Also, the BOSS Inlet Tube does not have provisions for an aspirator tube hook up that is common on automatic transmission equipped vehicles.
