Fitment and Application Details

Compatible with 1990-1992 Mercedes-Benz 300CE, valve cover to air filter, and 1990-1991 Mercedes-Benz 300SL, valve cover to air filter. This part number 1040941482 is also referenced as Mercedes-Benz OE 104 094 1482 for the same application. If you are replacing a cracked or oil-soaked Mercedes-Benz 300CE breather hose or a worn Mercedes-Benz 300SL crankcase breather hose, this molded hose is built to match the original routing and connection points.

What This Hose Helps Address

• Cracked or split crankcase breather hose
• Oil vapor leaks at the valve cover-to-air-filter connection
• Restricted crankcase ventilation flow
• Hydrocarbon emission control issues caused by hose failure
• Loose or deteriorated hose connections in the breather circuit

Installation Notes and Tips

Verify the hose routing against the original part before installation and confirm the end diameters match the vehicle connection points. This molded hose is intended for the valve cover to air filter path on the listed Mercedes-Benz applications, so inspect adjacent breather components for wear, oil saturation, or hardening before reassembly. Part number 1040941482 should be matched to the vehicle’s original configuration for proper fit.

Quality Assurance

URO backs this replacement hose with a 24-month unlimited mileage warranty. The hose is made from heat- and oil-resistant CR material and is engineered as a guaranteed-fit replacement for the specified Mercedes-Benz applications.
