These Big Mouth Throttle Bodies improve airflow for maximum performance. They bolt directly onto your existing LS intake, and with an opening nearly 40% larger than stock, they're a great upgrade.

Features and Benefits:
- Increased throttle blade thickness
- Offset throttle blade pivot
- 102mm opening
- Billet aluminum

Designed to maximize performance upgrades on all GM Gen III and Gen IV engines with cable-driven throttle bodies, the FAST 102mm Big Mouth Throttle Body with TPS and IAC is now available with an anodized black finish.

With an opening nearly 40% larger than stock, the FAST 102mm Big Mouth Throttle Body is ideal for use with the FAST LSXR, LSXRT, and LSXHR intake manifolds, as well as any other manifold with a 102mm or larger inlet. The FAST throttle body offers increased throttle blade thickness to eliminate deflection commonly found with other throttle bodies, especially those in boosted applications.

A smoother operating offset blade pivot improves throttle response, and a beefed-up linkage with a dual throttle spring mechanism ensures total throttle control. What’s more, FAST invested significant testing and engineering resources into optimizing cross-sectional flow and eliminating airflow turbulence, especially at part-throttle operation.
