The Genuine BMW Crankcase Vent Hose (part number 11-15-7-574-114) is an OEM replacement component designed to connect the crankcase breather system to the intake manifold. This hose plays a critical role in the positive crankcase ventilation (PCV) system by routing crankcase vapors back into the engine for combustion, helping to reduce emissions and maintain proper engine operation.
