Granatelli GM LS / LSX 105mm Natural Billet Drive-By-Wire Throttle Body | GMTBLS105

Give your GM LS or LSX engine the airflow it needs with the Granatelli GM LS / LSX 105mm Natural Billet Drive-By-Wire Throttle Body. Precision CNC-machined from 6061-T6 billet aluminum with a natural aluminum finish, this 105mm drive-by-wire throttle body is built for modified naturally aspirated and forced-induction combinations.

The 105mm bore steps up airflow capacity for big-cam, high-RPM and boosted LS combinations, and pairs with large-inlet intake manifolds such as the Granatelli ZILLA 105mm billet LS manifold.

105mm of Serious Airflow

Built for GM LS or LSX engine combinations that have outgrown the factory throttle body.

Key Features

Natural Aluminum Finish
