Granatelli 13-20 GM LT1/LT4/LT5 Drive-By-Wire 103mm Throttle Body - Black

Granatelli Motor Sports is known for making well-built performance parts for GM vehicles. This 103mm throttle body is a direct replacement for many GM cars and trucks equipped with LT1, LT4, and LT5 engines, including popular models like the Chevrolet Camaro, Corvette, and Silverado 1500. It's a drive-by-wire unit, meaning it uses an electronic signal from your accelerator pedal to control airflow, which is standard on modern GM vehicles.

This larger 103mm throttle body allows for significantly more air to enter your engine compared to the stock unit. More air means your engine can burn more fuel, which can lead to improved throttle response and overall power. The unit is finished in black for a clean look under the hood. It's designed as a direct fit, so installation should be straightforward for someone familiar with engine components, though you'll want to refer to the manufacturer's instructions for specific details.

When upgrading your throttle body, it's a good idea to ensure your other engine components are up to the task of handling the increased airflow. This throttle body is a solid option for those looking to enhance their LT-series engine's breathing capabilities. Please note that this part is not CARB approved and cannot be shipped to California.
