Granatelli Motor Sports LT1/LT4/LT5 Drive-By-Wire Billet Throttle Body GMTBLT112B

Granatelli Motor Sports is proud to offer a variety of performance throttle bodies for late model, drive-by-wire engines. Our throttle bodies are precision-machined to exceed the demands required for increased airflow on high performance applications, both naturally aspirated and forced induction. These upgraded throttle bodies can be used with factory or aftermarket manifolds and utilize the OEM harness connector. The increased size also allows for smoother and quicker engine acceleration--and there's no need to transfer anything over from the factory unit. Proper tuning is highly recommended after installation. Granatelli throttle bodies are available for hundreds of vehicles from the 1990s and up.

5.3 L models will need to run an aftermarket 6.2L style intake manifold
