BMW N54 Billet Coolant Port Fitting

Description

A simple but essential upgrade for anyone running custom cooling or single-turbo setups on BMW’s N54 engine. The BMS N54 Coolant Port Fitting replaces or adds a coolant connection at the rear of the cylinder head, providing a clean, secure way to route coolant lines for turbo water cooling, catch can integration, or other custom configurations.

Precision-machined from billet aluminum, this fitting offers a leak-free seal and long-term durability — perfect for high-temperature, high-boost environments where plastic or improvised fittings can fail. Whether you’re building a street car or a full custom turbo project, this is one of those small parts that makes the job right.
