Wilson Manifolds Throttle Bodies

Wilson Manifolds High Flow Throttle Bodies were developed using the latest computer modeling software and test equipment available to produce designs that yield the maximum flow per square inch of cross-sectional area. Fourbarrel style throttle bodies are designed to work with our line of billet spacers and incorporate a tapered and radiused throttle bore and precisely machined progressive linkage for smooth throttle operation. They also feature inward opening throttle blades to eliminate any part throttle directional influence by the blades that can cause poor air distribution. Our four-barrel throttle bodies are shorter in height than other brands by up to 1.25" for ease of packaging and reduced weight. 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. High flow throttle bodies are available in 4500 and 4150 four-barrel styles as well as many single bore sizes in Ford and LS1/LS6 designs.
