Granatelli 103mm black drive-by-wire throttle body for GM LS and LSX combinations using a factory-style six-pin connection. The body is precision-machined cast aluminum.
 
Its large bore supplies more inlet area for naturally aspirated or boosted engines. The electronic motor maintains throttle control at up to 35 psi of boost and resists unwanted blade movement. The complete assembly needs no internal components transferred from the old throttle body.
