New in the original Mopar box. AIS motor (Air Idle Speed) motor. This is what controls your idle.
This one is for the larger 52mm throttle body.
Mopar part number: 5277839
How do I know what size AIS motor my car has?
If you have a 2.2 Turbo II engine in your car....and it's 100% factory original...you have the smaller 48mm Throttle Body....and thus this AIS motor will NOT fit your car.
However, *******if you upgraded your Turbo II engine to the larger 52mm throttle body (e.g. off a 3.3L v6), then YES this AIS motor will fit your throttle body.
If you have a Spirit R/T or Iroc R/T....then YES this will fit your car because all Turbo III engines came with the larger 52mm throttle body from the factory.
If you have ever installed an aftermarket AIS motor in your Shelby/Dodge you know how crappy they are.
I really wish we could still get these from Mopar...but alas, they have been discontinued.
This is the last new OE Mopar AIS motor we have.
