FAST 4 Barrel Throttle Bodies incorporate tapered and radiused throttle bores and precisely machined progressive linkage for smooth throttle operation and unparalleled airflow. More airflow equals more horsepower. Shorter height for better airflow, easier packaging for tight hood clearance and reduced weight. Inward opening throttle blades increase performance by eliminating part throttle directional influence from the blades that can cause poor air distribution. Includes commonly available, GM-type TPS. Flows 2000 CFM. Red Anodized Version Also Available.
