Fast 102mm Big Mouth Billet Throttle Body 54107 – W/ IAC & TPS, Black
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 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.
