TCI Automotive 54104 102mm Big Mouth Electronic Throttle Body for GM LS Engines

102mm Big Mouth Electronic Throttle Body For GM LS Engines All the benefits of the current 102mm Big Mouth Throttle Body™ are now available for drive-by-wire applications, thanks to the new FAST™ 102mm Big Mouth Electronic Throttle Body for GM LS Engines. This new electronic throttle body maintains stock characteristics at idle while providing a huge increase in airflow over stock – especially when running a FAST manifold.

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 also 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 for boosted applications. Additionally, a dual return spring and a precision non-contact TPS increase reliability. The throttle body also features a stylish satin black anodized finish for excellent aesthetics and a unique look. Upgrade that stock throttle body and feel the difference.
