4 bolt 90mm Mechanical throttle body for LS engines.

When you run an LS engine, performance begins with the introduction of air into the intake manifold. MSD's new 90mm LS Throttle Body answers the need for a high quality throttle body with a mechanical throttle mechanism that bolts to most factory and aftermarket intakes. MSD went through the time and expense to develop a cast throttle body assembly in order to achieve a unique parabolic bore form. This design helps deliver excellent drivability characteristics during part throttle that typical billet straight bore throttles just can't deliver. We incorporated factory style bearings and seals on the throttle that can withstand years of use on the street or strip. *TPS and IAC not included.
