BILLET 90mm LS Throttle Body w/low RPM Taper
Type: Throttle Body
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!
