How often should I clean my AEM Dryflow filter?

Cleaning frequency depends on your driving conditions. Inspect the filter regularly, and clean it when you see a buildup of dirt and debris. AEM recommends cleaning every 25,000 to 50,000 miles for normal driving, or more often in dusty conditions.

What do I use to clean my AEM Dryflow filter?

AEM sells a cleaning kit specifically for Dryflow filters. It includes a cleaner formulated to remove dirt and debris without damaging the synthetic filter media. Regular soap and water are not recommended.

Does this filter require oiling?

No, the AEM Dryflow filter is designed to operate without oil. Oiling this filter can actually reduce its airflow and filtration efficiency, and may damage your vehicle's mass airflow sensor. Keep it dry for best results.
