Installation Notes and Tips

Verify the vehicle year, model, and HVAC filter location before ordering. Replace the cabin air filter according to the service schedule or sooner if airflow drops or the filter is visibly loaded with debris. Confirm the CF-66 application against the existing filter part number when servicing BMW X3, M3, and 3 Series models.
