Wilson Hi-Boost 105mm Billet Dual-Seal Throttle Body LS / Ford Pattern

New Silver version available for Pre-Order! Will ship March 1st 2026

Specifically developed for severe duty and high boost applications, the new Wilson Manifolds Hi-Boost 105mm Dual Seal Throttle Body design provides improved performance and durability. 

They started with a sealed shaft that is pressure tested to 100 psi and stable under the high engine temperatures and high inlet air temps seen in competition and high-power street applications. They redesigned the mounting coupler for the TPS sensor to eliminate erratic signals sometimes seen under high boost. The blade is then installed in a split-shaft for superior strength – counter-sunk mounting screws hold the blade in a contoured design for improved airflow at full throttle. Initially offered in the popular 105mm opening, additional sizes will be coming soon.
