With Holley Sniper throttle bodies, Holley engineers went back to the drawing board to build the ultimate air valve for your engine! They feature enlarged bore sizes, allowing for increased airflow to support your higher horsepower needs. A progressive throttle pulley enhances low-speed drivability, and a double return spring provides solid and secure throttle control feel. These units are maximized for your application, with a 4-bolt style mounting pattern; most models include bolts and gaskets. Order the throttle body designed for fitment with your year/make and engine family.
The Holley EFI die cast aluminum four barrel throttle body is designed to fit on any square bore (4150 or 4500 style) intake manifold. It has four 1.750 throttle plates and includes the Throttle Position Sensor (TPS), Intake Air Temperature Sensor (IAT), and Idle Air Control (IAC) motor. They feature non-progressive throttle linkage, for quickest throttle response, but can be converted to progressive operation with the purchase of Holley PN 20-122.
