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
The new FAST(TM) GM LS 102mm Big Mouth Electronic Throttle Body is designed to outperform all other aftermarket drive-by-wire throttle bodies for hi performance LS engines and look good in the process.
