Installation Guide

Installing the Mann Filter CF18211 Secondary Air Filter is straightforward and can be completed in a few simple steps:

1. Remove Existing Filter: Detach the current secondary filter by loosening the mounting screws or clips. Carefully lift the old filter out of its housing.
2. Inspect Housing: Check the filter chamber for debris or damage. Clean any accumulated dirt with a dry cloth to ensure optimal contact between the new filter and the housing walls.
3. Position New Filter: Align the CF18211 filter so that its edges match the mounting points. Ensure that the filter’s orientation matches the airflow direction indicated on the housing.
4. Secure Fasteners: Reattach the screws or clips, tightening them evenly to avoid uneven pressure that could compromise filtration performance.
5. Verify Seal: Inspect the seal around the filter edges. A snug fit prevents unfiltered air from bypassing the filter media.

Maintenance Tips

• Check the filter every 10,000 km or as recommended by your vehicle’s maintenance schedule.
• A visibly dirty or clogged filter should be replaced immediately to maintain engine efficiency and protect internal components.
• Store spare filters in a dry, dust‑free environment to preserve their integrity until installation.
