FAST® GM LS Big Mouth 102mm Throttle Body w/ TPS & IAC

These throttle bodies offer 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 and dual throttle spring mechanism ensure total throttle control. Constructed from billet aluminum, the FAST™ Big Mouth 102mm Throttle Body™ with TPS and IAC is designed to maximize performance upgrades on all Gen III and Gen IV engines with cable driven throttle bodies.
