Installation Guide

1. Preparation: Ensure the engine is cool and the vehicle is parked on level ground. Disconnect the battery if you prefer extra safety, though it is not mandatory for filter replacement.
2. Accessing the Filter Housing: Locate the air filter box under the hood. Remove any covers or brackets that may be securing the housing in place.
3. Removing the Old Filter: Gently lift the old filter out of its compartment, taking care not to spill any debris onto the engine bay.
4. Cleaning (Optional): If you wish to reuse the housing, wipe away dust with a clean cloth. Avoid using water or solvents that could damage seals.
5. Installing the New Filter: Place the MANN‑FILTER C 4371/1 into the housing, aligning it so that the airflow direction arrow points correctly. Secure any brackets or covers you removed earlier.
6. Final Check: Verify that the filter sits flush and that no gaps remain. Reconnect the battery if it was disconnected.

Maintenance Tips

• Check the filter every 12,000–15,000 km or annually, whichever comes first, especially in dusty or high‑traffic environments.
• A visibly dirty or clogged filter should be replaced immediately to avoid engine performance loss.
• Store spare filters in a dry, dust‑free location to preserve their integrity between replacements.
