Product Description

Specifically designed to fit 2014 GM LS3- and LSA-powered vehicles, the Granatelli GMTBLS3 delivers significant performance upgrades with its massive 103 mm bore. Built from aircraft-quality billet aluminum, it increases airflow up to 40% over the stock throttle body, improving throttle response and overall drivability.

This direct bolt-on unit installs easily using the factory GM 6-pin drive-by-wire connector, and requires no part transfers. Its high-torque servo design prevents throttle blade blow-back - even under boost applications up to 25 psi. Ideal for muscle cars, trucks, and SUV models equipped with the 6.2L V8, this throttle body is compatible with both factory and aftermarket intake systems.

Available in natural, polished, or black finishes, the GMTBLS3 includes everything you need for a clean installation. A custom calibration tune is recommended to optimize performance and ensure proper throttle response after installation.
