Holley Billet 90Mm Ls Throttle Body With Low Rpm Taper

Holley's BILLET LS Throttle Bodies stand out as the epitome of feature-loaded excellence. Holley meticulously reimagined the air valve for your LS engine, and the 112-589 throttle body, boasting a 90-millimeter bore with a low RPM drive-friendly taper, is the result. Innovative features such as Idle Bleed Adjustment, TPS CLOCKER, and a closable PCV Passage Valve make these throttle bodies the ultimate choice for straightforward installation and precise tuning. Whether you're running a stock LS engine, a turbocharged setup, a supercharger, or a high-performance cam engine, Holley's throttle bodies are optimized for your specific application.
