Product Description

The aFe 21-91155 Magnum FLOW Pro DRY S Universal Air Filter is a high-flow performance filter element crafted to enhance airflow and filtration efficiency in compatible aftermarket intake systems with a ~7" inlet flange. Its advanced oil-free synthetic Pro DRY S media delivers strong airflow while effectively capturing dust and contaminants - helping support improved engine breathing and throttle response compared with restrictive stock paper filters. The 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 21-91155 creates a secure, leak-free fit when clamped into performance intake openings. The conical design with deep, open pleats expands usable surface area for improved dust holding capacity and prolonged life. 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.
