Product Details

The Holley EFI Terminator X Stealth 4150 Throttle Body delivers a stealthy, high-performance EFI solution with a classic 4150-style flange pattern. Finished in sleek black, this throttle body seamlessly integrates electronic fuel injection with the traditional look of a carburetor, making it ideal for builders who want modern performance without sacrificing the vintage aesthetic.

Key Features:

  • 4150-style flange pattern for direct carburetor replacement compatibility
  • Four fuel injectors support up to 650 HP naturally aspirated or 600 HP with forced induction
  • Integrated kickdown provisions for Ford C4 and C6 transmissions
  • Compatible with GM TH350, TH400, 200R4, and 700R4 transmissions (kickdown provisions included)
  • Mopar 727 and 904 kickdown provisions available separately
  • Stealthy black finish maintains classic engine bay appearance
  • Designed for use with Holley Terminator X EFI systems

This throttle body provides the perfect balance of old-school looks and new-school technology, delivering improved throttle response, better fuel economy, and easier cold starts compared to traditional carburetors. The integrated transmission kickdown provisions simplify installation on popular automatic transmissions, eliminating the need for additional fabrication or adapters in most applications.
