MANN-FILTER C121331 Air Filter

The MANN‑FILTER C121331 is a high‑performance engine air filter designed to deliver optimal airflow and protection for modern passenger cars. Engineered with precision, this filter ensures that only clean, dry air reaches the combustion chamber, thereby enhancing fuel efficiency, reducing emissions, and extending engine life.

Key Features & Benefits

• Superior Filtration Efficiency: Utilises a multi‑layer media system that captures particles as small as 0.5 µm, providing up to 99.9% particle removal.
• Low Pressure Drop: Maintains high airflow with minimal resistance, which translates into better engine performance and lower fuel consumption.
• Durable Construction: Made from reinforced paper and synthetic fibers that resist moisture absorption and maintain structural integrity under varying temperature conditions.
• Easy Installation: Designed to fit a wide range of vehicle models, including the Mercedes‑Benz C‑Class (W204/S204), with a simple snap‑in mechanism.
• Long Service Life: Certified for up to 10,000 km in typical driving conditions before requiring replacement, reducing maintenance frequency.
• Eco‑Friendly Design: Manufactured using recyclable materials and processes that minimise environmental impact.

Technical Specifications

Installation Guide

1. Preparation: Ensure the engine is cool. Remove any debris from the filter housing and clean the mounting area with a dry cloth.
2. Positioning: Align the filter’s edge with the housing opening, ensuring that the airflow direction arrow points towards the engine.
3. Securing: Press firmly until the snap‑in clips engage. Verify that the filter sits flush against the housing walls.
4. Final Check: Inspect for any gaps or misalignments. Tighten any additional fasteners if required by the vehicle’s design.

Maintenance & Replacement Tips

• Inspect the filter every 5,000 km during routine maintenance to assess dirt accumulation.
• If you notice a significant drop in engine performance or increased fuel consumption, consider replacing the filter sooner than the recommended service life.
• Never use a damaged or torn filter; it compromises airflow and can lead to engine damage.
• Store spare filters in a dry, cool environment to preserve their integrity until installation.
