The AFS Ported 2021 Mustang GT Intake Manifold is the latest available, offering the same great results from the 2018+ design, with a black top sleeper option.  This modification for the 2011-23 Coyote engine adds power across the power band.  For 2018-21 Mustang GT owners, you have the option of purchasing our Ported version of your stock intake manifold for an additional 8-12hp and 7-9ft lbs of torque at points throughout the power band.

  • Direct replacement for 2018-2021 Mustang GT
  • Fits 2011-2017 5.0L Coyote engines (requires custom calibration)
  • Improved horsepower and torque in Gen 1/Gen 2 engines
Gen 1 11-14 engines will need MMR Lockouts to make the intake manifold compatible, which we sell and install for $50.  Gen 2 15-17 engines may require MMR Lockouts- please check with your tuner.  When installing the Ported 2018+ Mustang GT Intake Manifold on an F150, a MAP Sensor Modification may be needed for 2015+.

  • We cut and reshape the inlet and runners, removing excess glue in the seams and any obstructions to increase overall airflow and balance between cylinders.
  • For best results, ask us if we recommend pairing your Ported Intake Manifold with our AFS Ported Throttle Body. Our AFS Ported Throttle Body picks up an additional 5-7hp and 2-3ft lbs of torque with big gains and throttle response and mid-range torque you can feel.

      • (There are separate product pages for Gen 1 and Gen 2 Throttle Bodies.  The year of the throttle body must match the year of the vehicle’s computer and cannot be swapped out for different years like the intake manifold can be due to the electronics.)
