Yes, that is the factory BOV (also called the diverter valve, dump valve, etc.), and it can not be open to atmosphere, even with a filter on it, with the K-Jetronic fuel system, or it causes an extremely rich running condition. The curved spout on its end cap (the one you put a filter on) should have a hose that runs from it, down beneath the intake manifold, and to the downward curved pipe in the middle of the intake manifold (the combination pipe that also has the upward pointing straight pipe that the decel valve used to be connected to). It is hooked up the exact same way that it was with your original 3.0 setup.

What you have circled there is the cold start injector and I honestly do not know what the purpose of that air spout is (still trying to figure that out) or how it was originally connected. Do you remember what it was hooked up to with your 3.0 set-up? *edit* That spout is apparently the port for the AAV - the 3.3 manifold is a little different than the 3.0 and AAV port is on the other side - so yes, it needs to be plugged if you are not going to use the AAV.
