It's not necessary to have that part on.Coolant is used as a Starting fluid.(seriously)

It is a coolant/antifreeze reservoir that has nothing to do with the engine/radiator.

Mazda designed this system for extremely cold starts (subzero temps) it pumps a small amount of antifreeze in the intake, it was mainly useful in carbureted RX-7. These things fail often so I removed the line going to the intake and capped it off. Not too important but it's there for a reason. I live in Colorado and it gets cold but never had problems w/ out it.
