91 D21 KA24E Vacuum Leak out of unknown part

I have a nasty vacuum leak coming out of this thing. The problem is that I have no idea what this thing is or what it's called. Any help would be appricated.

I looked everywhere and couldn't find out what it is or does.

Thanks.

I think it might be an air induction valve box, the haynes manual i have doesnt even show it in there but ive seen one on my truck as well.

that is part of your emission system, (there is a air filter inside) that and the valves below it are subject to rusting out... as you know. I believe its called the "EAI" case & valves (exhaust/air/injection)(correct me if I am wrong)
