The Speedmaster throttle body begins as a billet of 6061- T6 aluminum for superior quality and is introduced to a state-of-the-art CNC machine. The quality of these throttle bodies are better than others available today. The body is alloy machined finish, looks beautiful when you pop the bonnet. These can be used on std or aftermarket plenum manifolds, that have a 4bolt pattern. The butterfly is fully adjustable, allow for perfect idle positioning. For the LS2 guys, be done with your flyby wire, and go back to the old school cable, dont let your computer decide how fast you go!!! Original LS1 Throttle position sensor and Idle Air Control can be used. By simply getting a tune, and exhaust the power gains are massive.
