4-Barrel Throttle Body (AM1012)

The Aces EFI 4-barrel throttle body (AM1012) is designed to fit any 4150-style intake manifold with the look of an old-school carburetor. Equipped with four 1-3/4” throttle plates within 1.75” bores for a total CFM rating of 1000, it acts as a competitively-priced, reliable replacement for a carburetor or comparable throttle body. The AM1012 is utilized in Aces’ multiport setups, where it acts as a significant improvement over the older AM1004 model thanks to its diecast construction and high-quality machining. Also incorporated into the throttle body are the Throttle Position Sensor (TPS), Manifold Absolute Pressure sensor (MAP), and Idle Air Control system (IAC). Whether you’re looking to replace a stock part or assemble your own bespoke system, the AM1012 stands at the ready to deliver quality performance at an affordable price. That’s the kind of combination you can only get by betting on Aces.
