Big Mouth LT Throttle BodiesT from FASTT are a perfect choice for a variety of GM LS applications. Features black-wrinkle powder coating and all of the same features as FASTT billet throttle bodies. The enlarged bore is a substantial upgrade over stock and allows increased airflow to support higher horsepower. A progressive throttle pulley enhances drivability, especially at low throttle, while a double return spring provides a solid feel and increased safety. A drive-by-cable throttle body (FASTT Big Mouth/Big Mouth LT) is necessary for XFIT and EZ-EFI® (or other aftermarket EFI customers) running an engine that was originally throttle-by-wire. Also available with GM-style IAC and TPS.
