The aFe Power Magnum FLOW Pro Dry S universal air filter delivers high-performance airflow with the convenience of an oil-free design. This conical filter utilizes three layers of progressively finer synthetic mesh media to achieve 99.2% filtration efficiency, ensuring your engine receives clean air while significantly reducing restriction compared to standard factory paper filters.

Engineered for durability, this filter is built with 100% polyurethane on all sides for a long service life. The pliable flange includes integrated bumps to ensure a secure, leak-proof seal over your intake tube. Maintenance is simplified because the Pro Dry S media requires no oil; the filter easily washes clean with soap and water for repeated use.
