Product Description

The aFe 21‑91059 Magnum FLOW Pro DRY S Universal Air Filter is a high‑flow performance filter element engineered to significantly improve airflow and filtration efficiency in compatible aftermarket intake systems featuring a ~8″ inlet flange. Its advanced Pro DRY S oil‑free synthetic media delivers strong 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 construction simplifies maintenance and reduces long‑term filter replacement costs.

Constructed with a pliable polyurethane flange with integrated bump seals and a rugged polyurethane top and base, the 21‑91059 creates a secure, leak‑free fit when clamped into performance intake openings. The deep, open pleat conical design increases usable surface area for improved 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 overall dimensions match your intake system before installation to ensure proper fit and performance.
