The aFe MagnumFLOW Pro DRY S Universal Conical Air Filter, Part Number 21-91068, is designed to deliver strong airflow and dependable filtration for a wide range of automotive intake applications. Its progressively layered synthetic media uses three levels of filtration between polyurethane top and base layers to provide a 99.2% filter efficiency while supporting the airflow needed for performance-oriented systems. The conical design and evenly spaced open pleats help maximize usable filter surface area and dust-holding capacity, allowing longer service intervals between cleanings.
The washable, reusable Pro DRY S media is engineered for convenient maintenance without the need for filter oil. When cleaning is required, the filter can be serviced with soap and water, then reused through multiple cleaning cycles. A durable 100% polyurethane frame on all sides helps maintain structural integrity over extended service life, while the pliable polyurethane flange and integrated sealing bumps promote a tight, no-leak fit when installed correctly. This combination of materials provides a dependable seal and helps protect the intake system from unfiltered air.
The aFe MagnumFLOW Pro DRY S Universal Air Filter is intended as a replacement intake filter for compatible custom and universal applications. Verify filter fitment and mounting requirements before installation, as the product is not CARB approved and may require acknowledgement for use in applicable locations. This product also carries a California Proposition 65 designation; review all applicable warnings before purchase and installation. With its high-flow media, reusable construction, and low-maintenance design, Part Number 21-91068 is a practical choice for drivers seeking efficient intake filtration and long-term serviceability.
