Accufab has developed Ford to GM IAC adapter. This Idle Air Control adapter makes it possible to use a GM Early model year (THREADED) or Late model year (NON-THREADED OR SMOOTH) Idle Air Control Motor on an Accufab, Ford style throttle body. This Ford to GM IAC adapter is available in Polished and Black, billet aluminum. 

Description

Ford to GM IAC adapter.

IMPORTANT: BEFORE ORDERING, PLEASE DOUBLE CHECK YOUR GM IDLE AIR CONTROL MOTOR TO SEE IF IT’S THREADED OR IF IT’S NON-THREADED, SMOOTH.

GM Early Style IAC Adapter – Our part number IACGM-1 allows a GM early model year “threaded” style GM IAC motor to be mounted on an Accufab, Ford 5.0L style (65mm through 105mm) throttle body. Includes adapter & IAC gasket. (Your GM motor will actually have threads on it and screw into this adapter, have a square connector with 4 connector cavities and no other fasteners are needed). Ford to GM IAC adapter only, sensor not included.

GM Late Style IAC Adapter – Our part number IACGM-2 allows a GM late model year “smooth, non-threaded push-in” style flat 4-pin GM Idle Air Control motor to be mounted on an Accufab, Ford 5.0L style (65mm through 105mm) throttle body. Includes adapter & gasket and two fasteners. (Your GM Idle Air Control motor doesn’t screw in, it simply pushes into the adapter, and has flat 4-pin oval connector. After it’s pushed in to the adapter, it’s held in place with two small fasteners). Ford to GM IAC adapter only, sensor not included.

  • Note: Chrysler Flat 4-pin Idle Air Control Motor is different than the GM Idle Air Control motor, although it looks identical, the bolt pattern to fasten the IAC motor to the adapter differs and does not bolt on to our adapter. Accufab does not recommend modifying the adapter to work with a Chrysler IAC Motor. Forcing it to fit, will strip the threads on the adapter.

    Great looking product, works perfectly. Makes for better idle stability with aftermarket ECU’S.

    Beautiful piece, all hardware included. I called with a concern that ended up having nothing to do with this piece, and I received a call back quickly, with the intention of making any issues correct. Great customer service as well.

    Having a scratch resistant black option would be cool. The part fits great

    Product is made nicely. But the way the holes are offset makes the sensor turn towards the throttle body and u can plug in sensor with it bolted on. So I had to turn the bracket I got from u upside down. To get it to work. Now accurate is upside down.

    You can make this work with the Chrysler style (Holley) IAC by slightly enlarging the bottom hole on the IAC. Don’t try to force the screw in, just modify the bottom hole on the IAC (leave the Accufab adapter as is)
    The Chrysler/Holley IAC flows more air and does not require repinning of the wire harness on HP or Dominator systems. Quality of this piece is outstanding. Just purchased a second one for another project we are doing.

    Without this adapter I’d have to cut my brand new Holley EFI wiring harness. And I really didn’t want to do that. Holley has the plug for gm even on the ford harness.

    Great fit and finish, used it with my Holley Dominator system and Holley’s IAC by elongating one of the mounting holes on the IAC. Wonderful product!
