Product Details

FAST GM LS Big Mouth LT Throttle Body (4-BOLT) 92MM W/ IAC & TPS

 

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. 

 

Product Details:

  • 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
  • Progressive throttle pulley enhances drivability, especially at low throttle
  • Double return spring provides a solid feel & increased safety
  • Also available without GM-style IAC & TPS
 
Notes: 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. Please inquire within for such options.
