Product Description

The aFe 21-91064 Magnum FLOW Pro DRY S Universal Air Filter is a high-flow performance filter element engineered to improve airflow and filtration efficiency in compatible aftermarket intake systems with a ~7" inlet flange. Featuring advanced Pro DRY S oil-free synthetic media, this filter delivers high airflow while effectively capturing dust and contaminants - helping support enhanced engine breathing and throttle response compared with restrictive stock paper filters. The washable and reusable design simplifies maintenance and extends service intervals, reducing long-term ownership cost.

Built with a pliable polyurethane flange featuring integrated bump seals and a rugged polyurethane top and base, the 21-91064 creates a secure, leak-free fit when clamped into performance intake openings. The conical shape and deep, open pleats increase usable surface area for improved dust holding capacity and longevity. Because this filter is a universal-fit element rather than vehicle-specific, always verify that the filter's flange size and overall dimensions match your intake system before installation to ensure proper fit and performance.
