What is this? (Engine part on '95 GTP)

I've got a 1995 Grand Prix GTP with the 3.4L DOHC engine.

This is located towards the rear of the engine near and underneath the edge of the valve cover.

Underneath the cast aluminum part where the rubber air intake (from the filter) ducting connects to the air intake manifold with a metal band screw clamp, there is a cast aluminum part where the metal radiator return tube (among others) hooks to. It is a separate piece that has the following raised numbers on top:

1012
7408

Can anyone tell me what this part is called, GM part code for it and where I might order one online (if possible)? It apparently has a leak in it (the connection fitting on it to one of the metal tubes cracked).

Thanks in advance for the help. I've learned a great deal from y'all by perusing the threads on this forum.

Just a guess, but it sounds like the lower intake manifold. If its leaking coolant, that would be my guess.

Thanks! I bet you're right. I'll put in a picture of it when I get home this evening if I don't have a positive ID by then.
