It sounds like the coolant filler neck?
You can buy a brand new one from the Mazda dealer.
It comes with a brand new radiator cap too.

Does yours have a bypass fitting?
If not, I'd recommend getting the FD part, as it's aluminum and will probably outlast the engine itself.

I would not chance a used one.
Used ones have a chance to be leaking.
I had one tiny crack in mines that you cannot see except for the telltale white residue from coolant drying up.

A brand new one is like $50 with cap, I think.
Cheap insurance.
