Product Description

The aFe 21-91044 Magnum FLOW Pro DRY S Universal Air Filter is a high-flow performance air filter element engineered to improve airflow and filtration efficiency in compatible aftermarket intake systems featuring a ~6" inlet flange. Its advanced Pro DRY S oil-free synthetic media allows excellent airflow while effectively capturing dust and contaminants, helping support improved engine breathing and throttle response compared with restrictive stock paper elements. The washable and reusable design makes routine maintenance simple and reduces long-term ownership costs.

Constructed with a pliable polyurethane flange with integrated bump seals and a rugged polyurethane top and base, the 21-91044 forms a secure, leak-free fit when clamped into compatible intake openings. The conical shape and deep, open pleat design increase usable surface area for enhanced dust holding capacity and longer service intervals. Because this filter is a universal-fit element rather than vehicle-specific, always verify that the filter's flange size and shape match your intake system before installation to ensure proper fit and performance.
