Big Mouth LT Billet Throttle Body w/ TPS & IAC

Specs:

Size: 87mm

Cost-Effective, but Stylish Alternative to CNC Billet Big Mouth Throttle Bodies

Big Mouth LT Throttle Bodies from FAST are a perfect choice for a variety of GM LS applications. Features black-wrinkle powder coating and all of the same features as FAST 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 (FAST Big Mouth/Big Mouth LT) is necessary for XFI and EZ-EFI (or other aftermarket EFI customers) running an engine that was originally throttle-by-wire. Also available without GM-style IAC and TPS.

Info Summary:

  • 92mm 4-bolt drive-by-cable GM LS throttle body
  • Black-wrinkle powder coating & all of the same functions as billet throttle bodies
  • Works excellently with LSX & LSXR intake manifolds as well as OEM 90mm intake manifolds
  • Drive-by-cable throttle bodies are necessary for XFI & EZ-EFI running an engine that was originally throttle-by-wire
  • Enlarged bore is a substantial upgrade over stock & allows increased airflow to support higher horsepower
