Product Description

The aFe 21-91153 Magnum FLOW Pro DRY S Universal Air Filter is a high-flow performance air filter element engineered to dramatically improve airflow and filtration efficiency in compatible aftermarket intake systems featuring a ~7" inlet flange. Its advanced Pro DRY S oil-free synthetic media delivers excellent airflow while effectively capturing dust and contaminants - supporting enhanced engine breathing and throttle response compared with restrictive stock paper filters. The washable and reusable design simplifies routine maintenance and extends service intervals, reducing long-term ownership costs.

Constructed with a pliable polyurethane flange featuring integrated bump seals and a rugged 100 % polyurethane top and base, the 21-91153 creates a secure, leak-free seal when clamped into performance intake openings. The conical shape with deep, open pleats increases 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.
