Product Description

The Granatelli GMTBLS3M is a Malevolent Series 103mm Drive-By-Wire throttle body for GM LS3, LSA, and LSX engines in DBW configuration. Cast from aluminum with a black finish, the 103mm bore delivers up to 50% more airflow over the factory unit for naturally aspirated and forced induction builds alike. The high-strength electric motor is specifically engineered to resist blade closure under up to 25 lbs of boost in both draw-through and blow-through supercharger configurations -- making this a go-to choice for TVS, Whipple, and Roots-style supercharger builds.

Requires a GM late model 6-pin connector, an intake with a 102mm or larger opening, and a tapered throttle body adapter. No parts transfer from the factory unit required. Professional tuning is required after installation. Not CARB legal -- for race/uncontrolled emissions applications only. Backed by Granatelli's 90-day limited warranty for street use applications.
