What hose connections must be connected on the stock '71 air cleaner for a 240Z to run correctly? For example the connection below the air cleaner intake.....I see some cars with nothing attached to it.

I am thinking of buying a Z Theraphy redone air cleaner and was curious which connections not currently connected that may have to be added. See my current setup below. I am hoping I can just swap out the air cleaner K & N element and bolt on the refurbished air cleaner.

on my 1972 car the 2 inch round connection just by the mouth of the intake attaches with an aluminium hose to a duct on the exhaust manifold, where the air cleaner draws hot air from when the winter setting is selected and the mouth of the air cleaner is blocked off.

hope it helps
