Genuine Mercedes-Benz Crankcase Breather Hose

This Genuine Mercedes-Benz crankcase breather hose (also called a PCV hose, crankcase ventilation hose or engine breather line) is an original equipment part. It carries crankcase vapors and blow-by gases from the engine block back to the intake system, where they are burned. This helps the engine's crankcase ventilation system work as designed.

Key Features:

• Original equipment part built to Mercedes-Benz specifications
• Helps manage crankcase pressure and route blow-by gases back to the intake
• Supports emissions control and helps limit oil leaks and seal stress
• Made to resist engine heat, oil vapors and under-hood conditions
• Designed to match the original connections for a straightforward replacement

A cracked, hardened or leaking breather hose can cause rough idle, vacuum leaks, oil seepage and check engine lights. Replacing it with a genuine part helps restore proper crankcase ventilation and keeps the engine running as the manufacturer intended. Choose the correct part number for your application from the available options.
