Product Description

The Granatelli GMTBLT4 is a 103mm drive-by-wire billet throttle body for GM LT1, LT4, and LT5 engines covering the 2014-2024 model range -- including the Camaro SS and ZL1, Corvette C7, Silverado, Sierra, Suburban, Tahoe, Yukon, and Escalade in 5.3L and 6.2L configurations. The 103mm bore is significantly larger than the OEM throttle body, delivering 40% more airflow at 7,000 RPM and dyno-proven gains of +20 RWHP and +17 lb-ft on a near-stock LT1 Camaro. CNC-machined from 6061-T6 billet aluminum, it uses the factory GM 6-pin connector for plug-and-play installation with no component transfer from the OEM unit and no ECU tune required for street use.

The electronic motors are rated for up to 25 lbs of boost in both draw-through and blow-through configurations, making this throttle body equally suited for naturally aspirated builds and forced induction applications. Best paired with an aftermarket intake manifold for a direct bolt-on install -- use with a factory intake requires the separate spacer part GMTBLTSPC. 5.3L applications require an aftermarket 6.2L-style intake manifold before installation. Does not fit 2020+ C8 Corvette. Not CARB approved. Black finish version available as GMTBLT4B. Made in the USA. 90-day limited warranty.
