Original MANN-FILTER Oil filter HU 711/6 z – Oil filter set with gasket / gasket set– For Passenger Cars

MANN‑FILTER Oil Filter HU 711/6 z – the definitive solution for maintaining optimal engine performance in a wide range of passenger cars, particularly those from Mercedes‑Benz and Infiniti.

Design & Construction

The HU 711/6 z is engineered with a robust, metal‑free filter element that delivers superior filtration efficiency while keeping the internal pressure drop low. Its compact dimensions (71 mm diameter) allow seamless installation in tight engine bays without compromising airflow.

The filter housing incorporates a high‑strength polymer shell that resists corrosion and thermal degradation, ensuring long‑term reliability even under high operating temperatures.

Filtration Performance

• Particle Retention: Captures 99.9 % of particles down to 0.5 µm, protecting the engine’s critical components such as pistons, valves, and bearings.
• Oil Quality Preservation: The advanced media structure traps contaminants that could otherwise cause wear or sludge formation, extending oil life and reducing maintenance intervals.
• Pressure Drop: Maintains a low pressure differential (0.5 psi) across the filter, preserving engine efficiency and fuel economy.

Compatibility & Fitment

The HU 711/6 z is specifically designed for:

• Mercedes‑Benz models: A‑Class, B‑Class, C‑Class (W204, W205), E‑Class, CLA, GLA, GLC, and related variants.
• Infiniti vehicles: Q30, Q50, and other models sharing the same engine bay layout.
• Other passenger cars with a 71 mm filter housing that match the OEM specifications.

Installation & Maintenance

The filter set includes a sealed gasket assembly, eliminating the need for additional sealing rings. This guarantees a leak‑free seal and simplifies the replacement process:

1. Remove the old filter by loosening the retaining clip.
1 Insert the new filter, ensuring the gasket faces the correct direction. 2 Tighten the clip to the manufacturer’s torque specification (typically 4.5 Nm). 3 Check for proper seating and absence of oil leaks before starting the engine.

Benefits Over Standard Filters

• Extended Oil Life: By trapping fine particles, the filter reduces sludge build‑up, allowing longer intervals between oil changes.
• Improved Engine Longevity: Consistent filtration protects pistons and valves from abrasive wear, contributing to a higher overall lifespan.
• Fuel Efficiency: Lower pressure drop means less work for the engine’s pump, translating into marginal fuel savings over time.
• Environmental Impact: Cleaner oil circulation reduces emissions of particulate matter, supporting stricter environmental regulations.

Quality Assurance & Compliance

The MANN‑FILTER HU 711/6 z complies with all relevant automotive standards, including:

• ISO 9001:2015 – Quality Management System certification.
• DIN 70020 – German standard for oil filters.
• OEM Approval – Endorsed by Mercedes‑Benz and Infiniti as a direct replacement for their original equipment.

Installation Tips for Optimal Performance

• Always clean the filter housing** before installation to remove any loose debris.
• Use a torque wrench** to achieve the correct tightening torque, preventing over‑tightening that could damage the gasket.
• After replacement, run the engine for a few minutes and inspect the oil dipstick for any signs of leakage or contamination.
