Metal Coolant Port Fitting Upgrade for BMW

This heavy-duty billet aluminum fitting is a metal direct replacement for the weak plastic factory coolant fitting which is prone to cracking and failure over time especially during disassembly. 

The factory plastic part heats and cools thousands of times and eventually becomes brittle and will crack and fail. Just a matter of time.
