Nick Williams is known for making some of the highest quality throttle bodies on the market. This is a great addition to the FAST LSXR 102mm Intake Manifold. This throttle body has a 4.23" OD, so you'll want to use a 4.25"coupler.* New LS2/LS3/LS7 version
* No harness required on LS2/LS3/LS7 applications
These throttle bodies are a great upgrade for naturally aspirated builds. We advise against using them in forced induction vehicles. Unfortunately, these pieces are not returnable once they have been installed. If you have any questions, please contact us prior to purchase.
