Factory Air Cleaner Assembly Part?

[syndicate1]

See the attached pic.... I’m running a fully stock set-up.

Does anyone know the name of this part?
What does it do?
How do I know if it should it be replaced?

In advance, thanks for your help!

Air temp control... Manifold vacuum to it and then connect it to the valve on the snorkel.

Cool air causes the vacuum to be able to pass to the snorkle valve, which closes, and that allows heated air from the heat stove around the Pass cast iron exhaust manifold into the carb to assist with warm up.

Is the part replaceable?

Believe the side with the vent on top goes over the tube connected to the little flapper.
