Holley EFI Billet 90mm LS Throttle Body w/Low RPM Taper – Black

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!

Holley is quickly becoming The New Standard In EFI! Holley’s HP ECU is standard equipment on the 2013/2014 Chevrolet COPO Camaro and Holley’s EFI throttle body powers every NASCAR Cup Series team. Top racers are making the switch to Holley EFI every day. Racers like Tom Bailey who set three new records and took the overall event win on the 2013 Hot Rod Magazine Drag Week and John Scali who used it to win the 2013 JEGS All Star race. But that’s not all. The world’s best street machine builders and tuners are making the switch to Holley EFI. Builders like Dave Lane who used Holley EFI to power the 2013 Goodguys Hot Rod of the Year and tuners like Steve Morris who use it to build some of the baddest forced induction beasts on the planet. It’s the easiest, most refined, feature-rich system that money can buy. But, don’t take our word for it, see what the best are saying about Holley EFI!
