4150 Billet, Black, Assassinator: 1215 cfm Throttle Body for EFI or Mechanical Injection

The Accufab " Assassionator"   four barrel 4150 throttle body is made from high quality 6061-T6 billet aluminum and then polished to a mirror finish, anodized black or red. Accufab's quality is second to none. Only the best components are used for unparalleled reliability and performance. Manufactured in the USA.

Easy to mount a Barrel Valve on to compare to the Terminator  style injector -  Progressive , easy to drive in the pits. 

The 4150 is a great street/strip throttle body.  It bolts up to so many intake manifolds and flows more air than most 4500 carburetors. Accufab’s 4150 throttle Body flows 1215 CFM and has four 1-3/4" brass throttle plates.

This model uses late model GM electronics (TPS and IAC) which are included. Also, the 4150 comes with progressive linkage.

Accessories Included: 4150 series throttle body includes a throttle body gasket, throttle position sensor (TPS) and idle air control sensor (IAC) with appropriate mounting screws.
