URO 11118619408PRM Aircraft-Grade Aluminum Coolant Outlet Flange for BMW B58 3.0L

The URO Parts 11118619408PRM is a premium aircraft-grade aluminum coolant outlet flange designed as a direct replacement for the factory-installed plastic composite unit found on BMW's Gen 1 B58 3.0L turbocharged engines. This engine block-mounted coolant hose flange serves as the critical connection point where coolant hoses attach to the engine's cooling circuit, maintaining proper coolant flow between the engine, radiator, and heater core.

The OEM flange is manufactured from a plastic composite material that is known to become brittle and fail over time — potentially resulting in coolant leaks and engine overheating. The URO PRM (Premium) series resolves this with an aircraft-quality aluminum construction that resists the warping, cracking, and thermal degradation that plagues the original plastic component.

Key Features:

• Aircraft-quality aluminum construction — resists warping and cracking that leads to dangerous coolant leakage
• Direct OE replacement — manufactured to OEM dimensions for a bolt-on fit with no modifications required
• Upgraded over OEM — aluminum build outlasts and outperforms the factory plastic composite flange
• ISO 9000 manufactured — produced in facilities adhering to the highest quality standards
• Includes new seal for installation (temperature sensor not included; original sensor can be reused)
• Lifetime unlimited mileage warranty — URO Premium parts are backed by A.P.A.'s industry-leading warranty
