How often should I clean the filter?

AEM recommends cleaning the Dryflow filter every 25,000 to 50,000 miles under normal driving conditions. If you drive in dusty environments, you may need to clean it more frequently. Regular cleaning maintains optimal airflow and filtration efficiency.

The AEM Dryflow filter is designed for easy cleaning. Simply use AEM's filter cleaner to remove dirt and debris, then rinse with water. Allow the filter to air dry completely before reinstalling it — no oiling required.
