Product Description

The aFe 21-91053 Magnum FLOW Pro DRY S Universal Air Filter is a high-flow performance air filter element engineered to significantly 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 exceptional airflow while effectively capturing dust and debris - providing enhanced engine breathing and responsiveness compared with restrictive stock paper filters. Its washable and reusable design simplifies maintenance and extends service intervals, reducing long-term ownership costs.

Constructed with a pliable polyurethane flange with integrated bump seals and a rugged polyurethane top and base, the 21-91053 creates a tight, leak-free fit when installed in performance intake openings. The conical shape and deep pleat design maximize usable surface area for increased dust holding capacity and longevity. Because this part is a universal-fit filter 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.
