Wilson Manifolds Hi-Boost Throttle Body 105mm

SKU: 471105xHB Categories: ,


4.250″ Bore


Wilson has updated their ever popular 105mm throttle bodies to the HI-BOOST (HB series) of performance throttle bodies. Specifically developed for severe duty and high boost applications, the new design provides improved performance and durability.

Wilson starts with a sealed shaft that is pressure tested to 100 psi and stable under the high engine temperatures seen in competition applications. Next, Wilson redesigned the mounting coupler for the TPS sensor to eliminate erratic signals sometimes seen under high boost. Then the blade is 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.  Available as a V-Band attachment or Dual Seal attachment.
