Product Description

The aFe 21-91108 Magnum FLOW Pro DRY S Universal Air Filter is a high-flow performance air filter engineered to enhance airflow and filtration efficiency in compatible aftermarket intake systems featuring a ~6" inlet flange. Its advanced Pro DRY S oil-free synthetic media provides excellent airflow while effectively capturing dust and contaminants - supporting improved engine breathing and throttle response compared with restrictive stock paper filters. The washable and reusable design simplifies routine maintenance and reduces long-term ownership costs.

Constructed with a pliable polyurethane flange featuring integrated bump seals and a rugged polyurethane top and base, the 21-91108 creates a secure, leak-free fit when clamped into performance intake openings. The conical shape with deep, open pleats increases usable surface area for enhanced dust holding capacity and extended service intervals. Because this filter is a universal-fit element rather than vehicle-specific, always verify that the filter's flange size and dimensions match your intake system before installation to ensure proper fit and performance.
