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 & 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
