BMW Crankcase Breather Hose (Part No. 11157533341)

The BMW Crankcase Breather Hose (Part No. 11157533341) is a vital component of your vehicle's positive crankcase ventilation (PCV) system. This hose is specifically designed to manage the flow of blow-by gases from the crankcase back into the intake manifold, where they can be re-burned, preventing harmful emissions and pressure buildup. A properly functioning breather hose is essential for maintaining optimal engine performance and longevity. It helps to regulate internal crankcase pressure, preventing the buildup of harmful gases and significantly reducing the risk of oil leaks from seals and gaskets. This ensures your engine operates efficiently and cleanly. Over time, these hoses can become brittle, crack, or clog due to heat and oil exposure, leading to various engine issues such as rough idling, increased oil consumption, or even engine damage. Replacing a worn or damaged breather hose with a genuine BMW part ensures a perfect fit, restores your engine's ventilation system to factory specifications, and helps avoid costly future repairs.
