Tech Tip: For 2017 GT Mustangs manufactured after 9/16, vacuum for the CMCV’s (Charge Motion Control Valves) is no longer picked up from the intake tube. This will require a plug to be used with the unused port/fitting on your new cold air intake tube when installing on all 2017 GT Mustangs built after 9/16 only. The production date on the vehicle (month/year) is located on decal in driver side door jamb.
