    4-Barrel Throttle Bodies

    FAST's 4-Barrel Throttle Bodies incorporate tapered and radiused throttle bores and precisely machined progressive linkage for smooth throttle operation and unparalleled airflow. Fits standard 4150 flange, and includes TPS, IAC and hardware. Supports flow up to 1375 cfm.


    • Inward opening throttle blades improve performance by eliminating part throttle directional influence that causes poor air distribution
    • Shorter height for better airflow, easier packaging for tight hood clearance and reduced weight
    • Brass throttle blades control vibration and reduce thermal expansion
    • Throttle blades attached to stainless steel shafts with aircraft-quality hardware and peened to ensure positive retention
    • Bodies are machined from 6061-T6 billet aluminum for consistent quality, excellent appearance, and light weight
