How often should I clean this filter?

AEM recommends cleaning the filter every 25,000 to 50,000 miles, depending on driving conditions. Inspect the filter regularly and clean it more often if you drive in dusty or off-road conditions. Proper maintenance ensures optimal airflow and filtration.

What is the filter media made of?

The AEM Dryflow filter uses a synthetic filter media. It's designed to provide a good balance of airflow, filtration, and engine protection. Because it's oil-free, it won't contaminate mass airflow sensors.

Is this filter legal in California?

No, this air filter is not CARB-approved and cannot be used on emissions-controlled vehicles in California. Check your local regulations before installing any aftermarket parts.
