Overview

Holley’s BILLET LS Throttle Bodies are the MOST FEATURE LOADED available. Holley went back to the drawing board and built the ultimate air valve for your LS engine! The 112-589 throttle body features a 90 millimeter bore and a low RPM drive friendly taper. Innovative features like Idle Bleed Adjustment, TPS CLOCKER, and closable PCV Passage Valve, make them the ultimate throttle bodies for ease of installation and tuning. Regardless of whether you have a stock LS engine, turbo, supercharger, or a big cam engine sucking gulps of air, Holley’s throttle bodies are maximized for your application. The barrier protection of the BLACK ANODIZED finish also offers up a modern tech look!

Features:

  • TPS CLOCKER allows the TPS to be rotated back into the ECU's required idle voltage range. Modified engines no longer suffer from problems related to TPS voltage!
  • IDLE BLEED allows adjustment of your idle without affecting throttle position or TPS voltages at idle!
  • PCV PASSAGE VALVE closes to accommodate forced induction applications! No more plugging to block off PCV!
  • TAPERED TRANSITION eliminates low RPM drivability issues
  • PREMIUM BILLET BODY supports the high tolerance design and look your performance engine deserves!
