Genuine BMW 11-15-8-647-299 Crankcase Breather Hose

The Genuine BMW 11-15-8-647-299 Crankcase Breather Hose is an original equipment manufacturer (OEM) replacement component designed to maintain proper crankcase ventilation in your BMW engine. This hose connects the crankcase ventilation system to the intake manifold, allowing blow-by gases and oil vapors to be routed back into the combustion chamber for reburning.

Key Features:

• Genuine BMW OEM part ensuring exact fit and function
• Constructed from high-quality rubber compounds resistant to oil, heat, and crankcase vapors
• Precision-engineered to meet BMW's strict quality standards
• Direct replacement for worn, cracked, or deteriorated original hose
• Helps maintain proper engine performance and emissions compliance

Over time, crankcase breather hoses can deteriorate from constant exposure to heat and oil vapors, leading to cracks, leaks, and potential vacuum leaks. A failing breather hose can cause rough idle, check engine lights, increased oil consumption, and failed emissions tests. Replacing this hose with a genuine BMW part ensures reliable operation and restores your engine's crankcase ventilation system to factory specifications.
