Genuine BMW 11-12-7-588-417 Crankcase Vent Hose

The Genuine BMW 11-12-7-588-417 Crankcase Vent Hose is an OEM replacement component designed to maintain proper positive crankcase ventilation (PCV) in your BMW engine. This hose routes crankcase gases from the engine block back into the intake system, preventing pressure buildup and reducing harmful emissions.

Key Features:

• Genuine BMW OEM part manufactured to factory specifications
• Precision-engineered for exact fit and optimal sealing
• Constructed from heat-resistant rubber compounds to withstand engine bay temperatures
• Prevents oil leaks and maintains proper engine ventilation
• Direct replacement for worn or cracked original hose

Over time, crankcase vent hoses can become brittle, crack, or collapse due to heat cycling and oil vapor exposure. A failing vent hose can cause rough idle, oil leaks, increased oil consumption, and check engine lights. This genuine BMW replacement ensures reliable operation and maintains your vehicle's emissions compliance.
