where is this going???
It's the air inlet for the Air Control Valve, here is the breakdown on what the ACV does.
AIR CONTROL VALVE - this is on the lower intake manifold, and the air pump feeds air into it. The ACV controls where the air pump's air goes - into the main cat, into the exhaust manifold, or into the silencer that's under the passenger side headlight. The '89-91 NA's have their 6-ports and VDI actuated from air pump pressure, so the ACV is required unless you fab something up. To remove the ACV, pull it off, remove the studs, put in a fresh gasket and a block-off plate. Make sure to cap off the vacuum lines that went to the ACV as well, and secure the wires up that went to it.

Hmm.. only one post?
I think we have a ringer on the forum.
Welcome..
It is the air outlet & you don't really need to connect it to anything.
Unless you have a very quiet exhaust, you can't even hear it.

That is the outlet for the ACV which goes to the air muffler thing below the front passenger headlight. Looks like you don't have it anymore, or at least don't have the hose connecting them.

yeah, once you have a mild tone exhaust you can remove the air silencer.. you wont be able to even hear it if you have an 'exhaust system'
OR just buy the block off plate from www.mazdatrix.com and bolt it up.
Unless it's an 89+, than your stuck with the stupid ACV

Sorry Owenxguo, Sureshot & Nz Convertible are correct it is the ACV Outlet, it was late last night when I posted my reply, you can buy block off plates from Mazdatrix.com for both the ACV and the EGR.
