thats the air boost valve if u didnt know that and if u have the stock intake there should be a port on the intake tube for it. as for the other port it should go to the purge cut-off silonoid valve.when i rebuilt mine i got a 92 teg intake mani that dont got the valve or ports,im sure i got a extra one layin around if u need one LMK, what year b18a1 is that

really no need to swap manifolds just cause the air boost valve is on there.

oh i see thanks for the help with that. would it be fine if i kept the air boost valve unhooked then, or should i plug it up?
and also, in the diagram it shows to solenoid valves, where my car only has one, so where should i connect the other plug on the back of the manifold to?

you can just cap off the unneeded ports at the back of the manifold.
