Yes it is, with my Y7 which has the same IACV position as the Y8 auto setup. I just took the TB off and than took the IACV off. It was just 4 small bolts (8mm or 9mm IIRC). there is a small o-ring like gasket going around it, so make sure you don't lose it or twist it, cuz you might be able to reuse it.

 

See if this helps at all

Automatic transmissions have them on the throttle body. Manual transmissions have them on the intake manifold.
