What It Helps Address

• Cracked or hardened crankcase breather hose material
• Vacuum leaks at the valve cover to intake tube connection
• Emission system routing issues caused by hose deterioration
• Oil vapor ventilation problems from a damaged breather line
• Fitment issues from non-OE-style replacement hoses

Installation Notes and Tips

Verify the hose routing, end style, and dimensions before installation. The EMH188 uses push-in ends and is specified for valve cover to intake tube placement on supported Mercedes-Benz applications. Confirm the inside diameter and centerline length against the original hose to ensure proper seating and routing. For best results, inspect nearby breather fittings and intake connections for wear before installing the replacement hose.
