How often should I clean my AEM Dryflow filter?

AEM recommends cleaning your Dryflow filter every 25,000 to 50,000 miles under normal driving conditions. If you drive in dusty or off-road conditions, you may need to clean it more frequently.

What do I use to clean the AEM Dryflow air filter?

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

Does this filter require oiling?

No, this AEM Dryflow filter is designed to operate without oil. Oiling is not necessary and can actually reduce airflow and filtration efficiency. It can also damage your mass airflow sensor.
