Show original supplier description
The Accufab 4150 throttle body is engineered for high-performance EFI conversions, offering a superior alternative to traditional carburetors. Crafted from durable billet aluminum, it is available in a mirror-polished finish or a choice of anodized black, blue, or red for a customized look. This throttle body boasts a 1215 CFM flow rate, supported by four 1-3/4" brass throttle plates and a progressive linkage system. It includes late-model GM electronics for the Throttle Position Sensor (TPS) and Idle Air Control (IAC) for seamless integration. The Accufab 4150 is designed to handle up to 20 psi of boost, though its shaft seals are not rated for applications exceeding this pressure; for higher boost levels, an elbow is recommended. Manufactured in the USA, the Accufab 4150 is built with uncompromising quality and reliability. It is designed to bolt up to many intake manifolds and offers greater airflow than most 4500 carburetors, making it an excellent choice for street/strip applications.
