Product Details

This is the Granatelli 103mm Drive-By-Wire Throttle Body, designed specifically for GM LS3, LSA, and LSX engines. If you're looking to get more air into your engine for improved performance, this is a solid option. It's built to handle the demands of these powerful GM V8s, and its larger 103mm bore allows for significantly more airflow compared to stock throttle bodies. This can translate into a more responsive throttle pedal and a noticeable increase in power, especially when paired with other engine modifications.

Granatelli has a reputation for well-built performance parts, and this throttle body is no exception. It features a natural aluminum finish and is constructed to be a direct replacement for many popular GM vehicles from 2008 through 2017 and beyond, including models like the Chevrolet Camaro, Corvette, and Cadillac CTS. The drive-by-wire system means it uses an electronic signal from the pedal to control the throttle plate, which is standard on these later model GM vehicles. Installation is typically straightforward, as it's designed to bolt right up to your existing intake manifold and connect to your factory wiring harness, though you may need to adjust your engine's computer settings to take full advantage of the increased airflow.

When upgrading your throttle body, it's important to consider that the engine's computer (ECU) will likely need to be tuned to properly manage the increased air volume. This ensures optimal performance and drivability. While this throttle body is not CARB approved and cannot be shipped to California, it's a popular choice for performance builds in other regions. Make sure to check your specific vehicle's fitment to confirm compatibility before ordering.
