SEMA 2014: Holley Performance Releases Their High Flow LS Throttle Bodies

HOLLEYTB-1If its one thing LS engine enthusiasts need when building a large-displacement or a boosted LS engine, it’s an efficient an unrestrictive intake charge. More airflow means more potential for more power.

Holley Performance is well aware of this fact, so when they suprised us at the 2014 SEMA Show with a pair of large-bore throttle bodies, we became ecstatic. Not only does this allow for two more viable options for building power, but it’s a bolt-on design that won’t take any additional effort on behalf of the engine builder.

Official Release:

Holley is proud to announce large bore EFI throttle bodies in 95mm and 105mm for GM LS 4-bolt intakes!

Holley’s LS Throttle Bodies are unquestionably 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 95 or 105 millimeter bore. The 95 mm version comes with a tapered bore to ensure low-RPM drivability. The 105 mm is available with the same taper, or a straight through bore for when WOT is all that matters!


The 105mm throttle body is available in two specifications; featuring a the same taper as the 95mm (see below), or smooth inlet designed for WOT bursts like the one pictured here.


Innovative features like Idle Bleed Adjustment, TPS CLOCKER, and fully adjustable 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. Plus, the BLACK ANODIZED finish offers up a modern tech look!
