There are some people out there who think that a throttle body is a flapper valve with no real impact on the performance of your engine. Those people are dumb for a multitude of reasons and these new pieces from Holley make our point for us. Holley went above and beyond on these new throttle bodies for LS four bolt intakes by adding a ton of features and patent pending design functions that help you better tune your car for the street or the race track.
There are three models available for purchase right now. The tapered 95mm throttle body is designed to have great street manners and high flowing track potential. The 105mm body is tapered and designed with bigger inch higher flowing applications and the straight through, no taper 105mm throttle body is designed for all out peak power applications like the drag strip, land speed racing, and other applications where the engine lives at WOT and needs to be making the most power possible.
With an adjustable PCV passage valve, integrated idle bleed adjustment screws, and the neat TPS clocker function that Holley is working on a patent for, your LS throttle body needs are covered by these three offerings.

HERE’S THE RELEASE FROM HOLLEY ON THESE NEW THROTTLE BODIES –
These feature-laden throttle bodies are constructed of billet aluminum to provide maximum durability and great looks. They feature a fully adjustable PCV passage valve that allows for fine tuning and accommodates forced induction applications where a PCV system is not used. An integrated idle bleed adjustment screw allows idle adjustment without affecting throttle position or TPS voltage. They also feature a patent-pending TPS clocker adjustment that allows you to rotate the TPS back into the ECU’s required voltage range to eliminate any TPS-related idle issues. The available tapered bores ensure great low-RPM drivability and power delivery, while the straight through 105 mm bore is reserved for applications where peak power is the only concern. The black anodized finish gives the throttle bodies a high-tech, subdued look that will complement any engine bay.
