Original MANN-FILTER Fuel filter WK 8039 – For Passenger Cars

MANN‑FILTER Fuel Filter WK 8039 – Technical Overview

The MANN‑FILTER Fuel Filter WK 8039 is a high‑performance, OEM‑grade component designed to protect the engine of passenger cars from contaminants in the fuel supply. Engineered with precision filtration media and robust construction, this filter ensures optimal fuel flow while extending the life of critical injection system parts.

Core Filtration Technology

The WK 8039 employs a multi‑layered filtration matrix that captures particles ranging from 0.5 µm to 10 µm in diameter. The inner layer is composed of a proprietary blend of cellulose and synthetic fibers, providing superior resistance to oil contamination and water ingress. This design guarantees:

• High retention efficiency for diesel and gasoline particulates.
• Low pressure drop, maintaining fuel system performance.
• Extended service life under normal operating conditions.

Material Composition and Durability

The filter housing is fabricated from high‑strength, corrosion‑resistant polypropylene. This material choice offers:

• Resistance to acidic fuel additives.
• Structural integrity at temperatures up to 120 °C.
• Lightweight construction for reduced vehicle weight.

Installation and Compatibility

The WK 8039 is engineered to fit seamlessly into a wide range of passenger car models, including but not limited to:

• Renault Logan (1.5 dCi)
• Dacia Duster (HS & HM variants)
• Sandero and other compact vehicles.

Its standardized 80 mm diameter and 7 mm flange thickness allow for straightforward installation using the vehicle’s existing fuel line fittings. The filter features a secure locking mechanism that prevents accidental disconnection during operation.

Performance Benefits

• Engine Protection: By trapping contaminants, the filter safeguards injectors, pumps, and valves from wear and clogging.
• Fuel Efficiency: Consistent fuel flow reduces engine load, contributing to better mileage.
• Reduced Emissions: Clean fuel promotes more complete combustion, lowering harmful exhaust outputs.

Maintenance Guidelines

While the WK 8039 is designed for longevity, regular inspection is recommended. Typical service intervals range from 15,000 to 30,000 miles, depending on driving conditions and fuel quality. Signs of wear include:

• Increased pressure drop across the filter.
• Visible clogging or discoloration of the media.
• Unusual engine noise or performance degradation.

Quality Assurance

MANN‑FILTER adheres to stringent European automotive standards, including E-Mark certification and compliance with ISO 9001. Each filter undergoes rigorous testing for:

• Filtration efficiency under simulated contamination loads.
• Pressure drop measurements across a range of flow rates.
• Durability against temperature cycling and chemical exposure.

Environmental Considerations

The WK 8039 is manufactured with sustainability in mind. The polypropylene housing is recyclable, and the filter media can be disposed of responsibly following local regulations. By extending engine component life, the filter also contributes to reduced waste generation over a vehicle’s lifespan.

Conclusion

The MANN‑FILTER Fuel Filter WK 8039 represents a blend of advanced filtration technology, durable construction, and proven performance. Ideal for passenger cars that demand reliable fuel system protection, this filter delivers consistent engine health, improved efficiency, and compliance with modern environmental standards.
