The Crankcase Vent/Breather Hose is an essential component located on the right side of the engine in BMW models, facilitating the proper circulation of gases between the crankcase and the intake system. This hose plays a critical role in maintaining optimal engine performance by preventing pressure buildup and promoting efficient air recycling. It directly interfaces with the engine's crankcase ventilation system, which helps to reduce emissions and improve fuel efficiency. OEM part number 8662604 is compatible with various BMW models including the M850i xDrive (2019-2024), M850i xDrive Gran Coupe (2020-2024), M550i xDrive (2019-2023), X5 (2019-2023), X7 (2019, 2020, 2023), and 750i xDrive, Alpina B7 (2020-2022). Signs of wear or damage, such as cracks or leaks in this hose, can lead to poor engine performance, increased emissions, or engine misfires, necessitating replacement. Commonly known as the Crankcase Breather Hose, this factory-original part ensures your vehicle operates as intended.
