Coolant Port Fitting Upgrade for BMW

This heavy-duty billet aluminum fitting is a direct replacement for the weak plastic factory coolant fitting which is prone to cracking and failure over time especially during disassembly. Replaces OEM part number 1537541992, 11537544638.

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