Affordable, Stylish Alternative to CNC Billet Big Mouth Throttle Bodies™

Consider the Big Mouth LT Throttle Bodies™ from FAST™ as a cost-effective yet stylish alternative for various GM LS applications. Boasting black-wrinkle powder coating and all the features found in FAST™ billet throttle bodies, this 92mm 4-bolt drive-by-cable GM LS throttle body ensures a significant upgrade over stock, allowing increased airflow to support higher horsepower. The progressive throttle pulley enhances drivability, particularly at low throttle settings, while the double return spring guarantees a solid feel and heightened safety. Serving as a drive-by-cable throttle body for XFI™ and EZ-EFI® systems (or other aftermarket EFI setups) on engines initially equipped with throttle-by-wire, it's also available with GM-style IAC and TPS.
