The 7.4L MPI L29 and 454 MAG MPI are distinct engine designations that use different IAC valves despite sharing the same displacement. Do not select by displacement alone.
This IAC valve applies to the 7.4L MPI L29 engine family. It is NOT the same IAC as the 454 MAG MPI / earlier EFI family (805224A1 / 8M0239245) or the ECM-555 / 496 / 8.1L family (862998 / 8M0181068). Verify your exact engine model, serial number, and existing OEM part number before ordering.
