Holley's BILLET LS Throttle Bodies are the BIGGEST BORE - MOST FEATURE LOADED available. Holley went back to the drawing board and built the ultimate air valve for your LS engine! This all new design boasts a huge 105 millimeter bore for when WOT is all that matters. 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 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!

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!
