Does this throttle body come with a new gasket or mounting hardware?

What is the benefit of a 105mm throttle body over a stock one?

About this part

Product Details

Granatelli Motor Sports is known for making well-built performance parts for GM vehicles. This 105mm throttle body is designed for GM's popular LS3, LSA, and LSX engines that use a drive-by-wire system. It's a direct replacement that can help improve airflow into your engine, which is crucial for making more power, especially if you've modified other parts of your engine like the intake or exhaust.

This throttle body features a 105mm bore, giving your engine a much larger opening for air compared to stock. The natural aluminum finish looks clean under the hood. It's built to fit right into the factory location on a wide range of GM vehicles, including models like the Chevrolet Camaro, Cadillac CTS, and Pontiac G8. Because it's a larger throttle body, it's often used in builds where the engine is making significantly more power than stock, or when upgrading to a forced induction setup.

When installing a larger throttle body, it's a good idea to have your engine's computer tuned to take full advantage of the increased airflow. This ensures the engine management system can properly meter fuel and air for optimal performance and drivability. This part is not CARB approved and cannot be shipped to California.
