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

This Granatelli 103mm throttle body is a direct replacement for many GM vehicles equipped with LT1, LT4, or LT5 engines. You get the throttle body unit itself, ready to install. It's a drive-by-wire unit, meaning it uses an electronic signal from the pedal to control the throttle plate, which is standard on most modern GM trucks and cars. If you're looking to get more air into your engine, especially if you've made other modifications, a larger throttle body like this can make a notable difference in how your engine breathes.

This throttle body is built with a 103mm bore, which is significantly larger than the stock unit on many LT-series engines. This increased diameter allows for a greater volume of air to enter the intake manifold, which can lead to improved throttle response and potentially more power, particularly when paired with other performance upgrades like intake systems or exhaust components. The natural finish on this unit is straightforward and functional, fitting right into the engine bay without drawing unnecessary attention. It's designed to be a direct fit, meaning it should bolt up to your existing intake manifold and connect to your factory wiring harness without major modifications.

When installing a larger throttle body, it's always a good idea to check your vehicle's specific requirements. While this unit is designed as a direct replacement for many popular GM models like the Chevrolet Camaro, Corvette, and Silverado 1500, as well as Cadillac Escalade and GMC Sierra, it's crucial to confirm fitment for your exact year and model. Some applications might benefit from a tune to take full advantage of the increased airflow, ensuring the engine's computer can properly manage the new air volume for optimal performance and drivability. Please note that this part is not CARB approved and cannot be shipped to California.
