Wilson Manifolds 471105 - 105mm Throttle Body 1520 CFM - 4.250" OD

Wilson Manifolds 105mm Throttle Body - 4.250" OD  All throttle bodies feature brass throttle blades to control vibration and reduce thermal expansion Throttle blades are fastened to the throttle shaft using aircraft quality hardware that is both Loctited and peened to assure positive retention of the blades. Throttle shafts are machined to decrease their cross-sectional area, which increases the actual cross-section available for airflow. All throttle bodies are machined from billet 6061-T6 aluminum on precision CNC machining centers for consistent quality and light weight.
