Simplify maintenance without sacrificing performance with the aFe 21-91035 Magnum FLOW Pro DRY S Air Filter. Engineered for maximum airflow and oil-free convenience, this inverted top conical air filter uses three layers of progressively finer synthetic mesh media to deliver 99.2% filtration efficiency—all without the mess of oiling.
Constructed with a 100% polyurethane top and base, the filter offers excellent durability and a pliable flange with integrated bump seals to ensure a tight, leak-free fit. The deep, evenly spaced pleats extend dust holding capacity and service intervals, while the inverted top adds more surface area for increased performance. Best of all, it’s washable and reusable for multiple cleaning cycles, making it a smart, long-term upgrade for performance-driven builds.
