This Speedmaster billet throttle body is engineered to deliver smooth, stable airflow across the rpm range. Machined from a 6061-T6 aluminum billet on CNC equipment, it features radiused inlet openings and bearing-mounted butterfly shafts for consistent throttle action. A shorter overall height helps packaging in tight hood-clearance applications while reducing weight. Includes billet arms and stops, with provision for a TPS on the unit.
