Wilson High Flow 4150 Throttle Body — NEW


The NEW 4150 Billet Throttle Body was designed with one goal in mind… Air Supremacy! Capable of delivering over 1500cfm, this is the highest flowing 4-blade 4150 throttle body on the market today.

This new design’s Stainless Steel 3-Way Adjustable Linkage connects to 3/8″ Throttle Shafts that ride on Sealed Roller Bearings instead of bushings that wear out and leak over time.

  • Throttle bodies feature inward opening throttle blades to eliminate any part throttle directional influence by the blades that can cause poor air distribution
  • All throttle bodies feature brass throttle blades to control vibration and reduce thermal expansion
  • Throttle blades are fastened to the throttle shaft using aircraft quality hardware that is both Loctited and peened to assure positive retention of the blades
  • 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
  • Includes IAC, TPS & Air Temp Sensors built into the body to ease installation!
