New at Summit Racing: FAST Big Mouth LT Throttle Bodies for 2011-17 Mustang GT
Running a FAST XFI, EZ-EFI, or other aftermarket EFI system that requires a cable-drive throttle body? Then you’ll like FAST’s Big Mouth LT Throttle Bodies. They have all of the go-fast features of FAST’s billet throttle bodies—large 87mm bore for more airflow, progressive throttle pulley for better low-rpm drivability, and a double-return spring for safety—all wrapped up in a black wrinkle powdercoated cast aluminum body.
The Big Mouth LT Throttle Bodies fit the OEM Coyote 5.0 intake manifold and the Ford Racing Boss 302R manifold. You can get one with or without the required GM style Idle Air Control (IAC) and Throttle Position sensor (TPS).
