What is a Billet Throttle Body? A billet throttle body is CNC-machined from a solid block of aluminum, resulting in a much stronger, lighter, and more precise component than cast OEM throttle bodies. The larger 52mm bore allows for greater airflow, making it a must-have upgrade for serious racers looking to unlock maximum performance.
