AFS GT350/Bullitt Ported Intake Manifold (11-22 Mustang)

AFS cut and reshape the inlet and runners, removing excess glue in the seams and any obstructions to increase overall airflow and balance between cylinders.

 

Yields: 5-7hp gain and 3-6ft lbs of torque, depending on your build.

 

AFS recommends throttle body porting for best results.  The GT350 TB porting is $200 usually, but you get a discount if you get the intake and throttle body ported together, so it would only be $160.  The throttle body would remain at 87mm to aide in ease of tuning; the inlet/outlet tapers are changed, throttle shaft is thinned, and throttle blade is modified.  The throttle body ported yields 321-325%CFM increase in flow and can run on a stock tune.  If you already have a tune or are planning to have a tune, AFS only guarantees tuning by Palm Beach Dyno or VMP, because this is not your average tune, you would need to make sure you have a reputable tuner.  The ported throttle body picks up an additional 5-7hp and 7-9ft lbs of torque with big gains and throttle response and mid-range torque you can feel.
