How do I clean the aFe Pro Dry S air filter?

aFe recommends using their POWER CLEANER to clean and recharge the Pro Dry S filter. Since it's an oil-free filter, you don't need to oil it after cleaning. Just spray it with the cleaner, rinse, and let it dry.

What are the benefits of using an oil-free air filter?

Oil-free air filters are easier to maintain because you don't have to worry about properly oiling the filter after cleaning. Oiled filters can cause issues if they're over-oiled, which can damage mass airflow sensors.

Is this air filter street legal in all states?

This air filter is not CARB (California Air Resources Board) approved, so it cannot be sold or installed on vehicles registered in California. Check your local regulations for compliance.

Product Details

This filter features three layers of oil-free synthetic media and requires no oil during maintenance to provide maximum convenience. Its progressive layering provides great filtration efficiency and dust holding capacity. This media is best suited for street use. Pro DRY S filters are easily recharged with aFe's POWER CLEANER. Click here for more information about our filter media. aFe POWER performance air filters use a rounded, evenly spaced pleat design which allows for more usable filter surface area, providing increased flow and greater dust holding capacity. This pliable sealing surface conforms to even the most uneven filter housing, making for a perfect filter fit and sealing surface every time. This design eliminates the use of gaskets or sealants and always goes back to its original form. All aFe POWER flat panel performance air filters are constructed with a full 360-degree polyurethane frame. Unlike other materials that degrade after repeated heat cycles in an engine bay, polyurethane maintains its original molded shape.
