Original MANN-FILTER Air Filter C 27 004 – For Passenger Cars

Product Overview

The MANN‑FILTER Air Filter C 27 004 is a premium engine air filter designed for passenger cars. It delivers superior filtration performance while maintaining optimal airflow, ensuring that the engine receives clean, dry air for efficient combustion and longevity.

Key Features & Benefits

• High‑Efficiency Filtration: Utilises a multi‑layer media system that captures fine particulates down to 0.3 µm, protecting the engine from dirt, dust, and contaminants.
• Optimised Airflow: Engineered with an aerodynamically balanced design that reduces resistance, allowing the engine to draw air at its maximum capacity without compromising filtration.
• Durable Construction: Made from high‑grade synthetic fibers and reinforced with a protective outer shell, the filter resists moisture absorption and maintains structural integrity over extended periods.
• OEM Compatibility: Meets or exceeds original equipment specifications for a wide range of vehicles, ensuring seamless fitment and performance parity with factory components.
• Easy Installation & Removal: Features a straightforward snap‑fit mounting system that allows quick replacement without the need for special tools.
• Long Service Life: Designed to stay clean longer than standard filters, reducing maintenance frequency while preserving engine efficiency.

Technical Specifications

Vehicle Compatibility

The C 27 004 filter is engineered to fit a broad spectrum of passenger cars. Commonly matched models include:

• MERCEDES‑BENZ A‑CLASS (W176), B‑CLASS (W246, W242)
• CLA Coupe (C117), GLA (X156)
• INFINITI Q30/QX30
• NISSAN models that share the same air intake architecture
• Other OEM vehicles with a 58 × 262 × 177 mm filter cavity

Installation Guide

1. Prepare the Vehicle: Park on level ground, engage the parking brake, and allow the engine to cool.
2. Locate the Air Filter Box: Open the hood and identify the rectangular air filter housing.
3. Remove the Old Filter: Unscrew or unlatch the cover, lift out the worn filter, and discard it responsibly.
4. Insert the New Filter: Align the C 27 004 with the airflow direction indicator (arrow on the side) and slide it into place until fully seated.
5. Secure the Cover: Replace the housing cover, tightening screws or latches to ensure a seal against dust ingress.
6. Check for Leaks: Verify that no air escapes around the filter edges; adjust if necessary.

Maintenance & Longevity Tips

• Inspect the filter every 10,000 km or after exposure to harsh environments (dusty roads, construction sites).
• Clean the outer housing with a damp cloth; avoid using solvents that could damage seals.
• Avoid forcing air through a clogged filter—this can reduce engine performance and increase fuel consumption.
• Store spare filters in a dry, sealed container to preserve their integrity until needed.

Performance Impact

By maintaining optimal airflow and filtration quality, the C 27 004 contributes to:

• Improved Fuel Efficiency: Cleaner air reduces combustion inefficiencies, leading to modest fuel savings.
• Enhanced Engine Longevity: Protection against abrasive particles minimizes wear on pistons, valves, and bearings.
• Consistent Power Output: Stable airflow ensures that the engine can deliver its rated horsepower without throttling due to restricted intake.
• Reduced Emissions: Efficient combustion lowers exhaust pollutant levels, supporting compliance with environmental regulations.

Quality Assurance & Manufacturing Standards

The filter is produced in a controlled environment adhering to MANN‑FILTER’s strict quality protocols. Each batch undergoes:

• Particle Filtration Testing: Verification against ISO 16890 standards.
• Airflow Resistance Measurement: Ensuring compliance with DIN 51608.
• Durability Trials: Simulating extended use under varying temperature and humidity conditions.
• Material Certification: Confirmation of synthetic fiber composition and resistance to oil, water, and chemical exposure.

Environmental Considerations

The C 27 004 is designed with sustainability in mind:

• Uses recyclable materials where possible.
• Reduces the frequency of filter changes, thereby lowering waste generation.
• Supports vehicle emissions reduction through efficient combustion.

Conclusion

The MANN‑FILTER Air Filter C 27 004 stands out as a reliable, high‑performance component for passenger cars. Its blend of advanced filtration technology, robust construction, and OEM compatibility makes it an essential upgrade for drivers seeking to protect their engines while maintaining peak performance.
