This Speedmaster billet throttle body kit is engineered to provide smooth, stable airflow across the rpm range. CNC machined from 6061-T6 billet aluminum, it features radiused inlet openings and bearing-mounted butterfly shafts for consistent throttle action. Brass throttle blades help control vibration and reduce thermal expansion, while a shorter overall height supports tight hood-clearance packaging and reduced weight. Includes billet arms and stops, with TPS and IAC included for MPI applications.
