Burger Motorsports BMS BMW N54/N53 Alloy Coolant Water Outlet/Neck Hose Connector & Flange – E82 E88 E89 E90 E91 E92 E93 E60 E61 X3 E83 135i 335i 528i 1M Z4 – CNC Billet Aluminium Radiator Hose Adapter – Replaces OE 11537544638, 1537541992

Alloy Water Outlet Connector for BMW N54 and N53 Engines

Eliminate coolant seepage at a notorious weak point with this CNC machined billet aluminium water outlet connector. Designed for E-series BMW applications running N54 or N53 powerplants, this precision-made metal outlet replaces the fragile factory plastic union that hardens and splits with age and heat cycles. A smart reliability upgrade for spirited road cars, tuned builds and daily drivers that want long-term cooling system security.

Looking for a metal water neck for your E90 or E92, an alloy radiator hose adapter for a 135i, a coolant hose connector to replace OE 11537544638, or a heavy-duty coolant spigot for an N54 or N53 engine bay? This is the direct swap you want. It is a tidy fit, engineered for durability, and helps prevent overheating caused by coolant loss at the hose outlet.

Key benefits

• Replaces the OE plastic coolant hose connector that often cracks and leaks
