MSD's 90mm LS Throttle Body delivers the air introduction that starts performance on LS-based engines, using a mechanical throttle mechanism that bolts to most factory and aftermarket intakes. A cast throttle body assembly achieves a unique parabolic bore form for excellent drivability at part throttle that typical billet straight-bore throttles can't match, and factory-style bearings and seals are built to withstand years of street or strip use.
