Original MANN-FILTER Air Filter C 18 003 – For Passenger Cars

MANN‑FILTER Air Filter C 18 003 – Premium Engine Protection

The MANN‑FILTER Air Filter C 18 003 is a high‑performance, OEM‑specification air filter designed specifically for passenger cars. It delivers superior filtration efficiency while maintaining optimal airflow, ensuring that the engine receives clean, dry air for maximum power and longevity.

Key Features & Benefits

• Ultra‑Fine Filtration: Utilises a multi‑layer media system that captures particles as small as 0.5 µm, protecting the combustion chamber from dirt, dust and contaminants.
• Optimised Airflow: Engineered to minimise pressure drop, which keeps fuel consumption low and engine response sharp.
• Durable Construction: Made with high‑quality synthetic fibers that resist moisture absorption and maintain structural integrity over extended periods.
• Easy Installation: Fits standard filter housings without modification; the design includes a secure mounting system for quick, tool‑free replacement.
• Long Service Life: Rated for up to 12 000 km of operation under normal driving conditions, reducing maintenance frequency.
• OEM Compatibility: Meets or exceeds original equipment manufacturer specifications for a wide range of passenger vehicles.

Technical Specifications

Installation Guide

1. Prepare the Vehicle: Park on a level surface, engage the parking brake and disconnect the battery for safety.
2. Remove Old Filter: Open the air filter housing, release any clips or screws, and carefully lift out the worn filter.
3. Inspect Housing: Clean any debris from the filter chamber to prevent contamination during installation.
4. Insert New Filter: Place the C 18 003 into the housing, ensuring that it sits flush against the mounting surface.
5. Secure Fasteners: Reattach clips or screws and tighten to manufacturer specifications.
6. Reconnect Battery & Test: Restore battery connection, start the engine, and verify that there are no leaks or abnormal noises.

Maintenance Tips

• Check the filter visually every 6 000 km; if it appears dusty or clogged, replace sooner.
• Avoid using water to clean the filter; moisture can degrade the synthetic fibers and reduce airflow.
• Store spare filters in a dry, cool environment to preserve their integrity.
• When replacing, always use an OEM‑approved part such as the C 18 003 to maintain engine performance and warranty compliance.
