The Accufab four barrel 4150 throttle body with integrated fuel rails is made from high quality 6061-T6 billet aluminum and anodized in black. This four barrel throttle body with fuel rails can be used on a carbureted manifold without modification for fuel injection. It flows the same as a regular 4150 four barrel.

Fuel injectors are not included. It is compatible with Siemens Deka shortie injectors. 

Accufab's quality is second to none. Only the best components are used for unparalleled reliability and performance. Manufactured in the USA.

This 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, and fuel rails.

We offer an idle air control block off plate. It's available polished, anodized black or red.
