URO 117-094-01-91 Crankcase Breather Hose Valve Cover to Air Filter

The URO 117-094-01-91 crankcase breather hose is a direct replacement for Mercedes-Benz engines, designed to restore proper crankcase ventilation system functionality. This critical component connects the valve cover to the air filter housing, allowing crankcase gases to be safely recirculated back into the engine intake system.

Key Features:

• High-quality rubber construction resists cracking and splitting from engine heat and oil vapor exposure
• Direct OEM replacement that meets or exceeds original equipment specifications
• Restores proper crankcase breather functionality for hydrocarbon emission control
• Manufactured by URO Parts, a trusted supplier of European vehicle replacement components
• Precision-engineered for accurate fit and reliable performance

A failing breather hose can cause rough idle, hard starting, check engine lights, and fuel trim faults. Replacing worn or cracked breather hoses maintains proper engine performance and prevents oil leaks in the crankcase ventilation system.
