Granatelli 105mm drive-by-wire throttle body for GM LS and LSX engines using a factory-style six-pin throttle connection and a compatible 105mm-inlet manifold. CNC-machined 6061-T6 billet aluminum with a natural finish.
 
The larger opening gives high-airflow naturally aspirated and boosted combinations more inlet area than a factory-size throttle body. The complete electronic assembly retains drive-by-wire control without transferring internal parts from the original unit.
