Electronic Fuel Injection (EFI)

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. These 4-barrel style throttle bodies are designed to work with Wilson Manifolds' 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 directional influence caused by the blades. Wilson Manifolds' 4-barrel throttle bodies are shorter in height than other brands by up to 1.25 in. for easy packaging and reduced weight. All throttle bodies feature brass throttle blades to control vibration and reduce thermal expansion. The throttle blades are fastened to the throttle shaft using aircraft-quality hardware that is both Loctited and peened to ensure positive retention of the blades. The 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.
