Holley 112-576 - Holley Throttle Bodies for LS1/LS2

Holley billet throttle bodies are CNC-machined out of billet aluminum to exact tolerances. Holley protects the billet aluminum with a clear anodized finish so each throttle body will retain its brilliant finish for many years to come. Holley's LS1/LS2 throttle bodies use hardened throttle shafts riding on ball bearings that make the throttle response ultra smooth from idle to wide open throttle. Ready to bolt on, this product includes hardware and complete instructions making the installation a simple process for the novice to experienced enthusiast.

The increased surface areas of the 80mm and 90mm throttle bodies allow more air into the engine for instant power gains at wide open throttle, plus OE throttle bore contour design is retained so low RPM partial throttle drivability is not sacrificed.

Note: Will not work on Drive By Wire Applications.
