Granatelli 103mm polished drive-by-wire throttle body for GM LS and LSX applications with a matching six-pin throttle-control system. CNC-machined from 6061-T6 billet aluminum.
 
A larger inlet gives a modified LS more room to breathe while retaining electronic throttle control. The high-torque servo and complete throttle assembly have been tested at up to 25 psi of boost, so the motor can control the blade under pressure.
