Genuine BMW Crankcase Vent Hose

The Genuine BMW Crankcase Vent Hose is an original equipment engine crankcase breather hose. It is part of the crankcase ventilation system, which routes blow-by gases and vapors from the crankcase back to the intake so they can be burned instead of released. A crankcase vent hose is also called a crankcase breather hose, PCV hose, or engine ventilation hose.

Key Features:

• Genuine BMW original equipment part built to factory specifications
• Helps the crankcase ventilation system manage internal engine pressure
• Made to resist heat, oil, and engine vapors
• Designed for a precise factory fit and reliable sealing at the connections

Replacing a cracked, brittle, or leaking vent hose with a genuine BMW part helps restore proper crankcase ventilation. It can also help prevent vacuum leaks, oil seepage, and rough running. Select the child item that matches your required part number.
