Description

All the benefits of the current Big Mouth 102mm Throttle Body(TM) are now available for drive-by-wire applications, thanks to the new FAST(TM) 102mm Electronic Throttle Body for GM LS Engines. This new electronic throttle body provides a huge increase in airflow over stock – especially when running a FAST manifold. However, it maintains stock characteristics at idle. The electronic throttle body is designed to be plug-and-play for most stock Gen IV LS ECUs including but not limited to L76, L77, L99, LS3, or LS7. It works well with the Edelbrock ProFlo4+ or any aftermarket EFI system designed to control a GM LS-style electronic throttle body. A high-performance, high-torque motor delivers a quicker response over competitors' weaker stock motors and features a rock-steady throttle blade in for boosted applications. Additionally, utilizing a dual return spring and a precision non-contact TPS increases reliability, the throttle body also features a stylish satin black anodized finish for excellent aesthetics and a unique look. The FAST(TM) 102mm Electronic Throttle Body for GM LS Engines does not use any stock components and has been designed for increased performance and reliability.
