Aeroflow’s Throttle bodies are a true billet construction
The 1375CFM throttle bodies utilise dual pattern flange (4150 & 4500) and incorporate the idle air control valve (IAC) and throttle position sensor (TPS)
The 175 bore is designed with a special radius which promotes maximum air flow and minimum turbulence
Will Fit on both 4150 / 4500 FLANGE Intake Manifolds
