FAST Big Mouth LT 92mm Throttle Body w/ IAC & TPS (GM LS)

Big Mouth LT Throttle Bodies from FAST are a cost-effective option to the original billet Big Mouth Throttle Body and are available for GM LS, Ford Coyote and Chrysler Hemi applications. The 92mm LSX version is the perfect choice for a variety of LS applications, while the 87mm throttle body is built specifically for Ford Coyote and Chrysler Hemi engines. Each 4-bolt style throttle body features black-wrinkle powder coating and all of the same features as FAST billet throttle bodies. The enlarged bore on each component 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 solid feel and increased reliability. A FAST Big Mouth LT Throttle Body is necessary for XFI and EZ-EFI (or other aftermarket EFI customers) running an engine that was originally throttle-by-wire. Available with or without GM-style IAC and TPS.

For LS 4-bolt applications or those equipped with LSX/LSXR Intake Manifolds.
