Product Description

The aFe 21-91092 Magnum FLOW Pro DRY S Universal Air Filter is a high-flow performance air filter element engineered to enhance airflow and filtration efficiency in compatible aftermarket intake systems featuring a ~7" inlet flange. Its advanced Pro DRY S oil-free synthetic media provides excellent 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 ongoing filter replacement costs over time.

Constructed with a pliable polyurethane flange with integrated bump seals and a rugged polyurethane top and base, the 21-91092 creates a secure, leak-free seal when clamped into performance intake openings. The conical design with deep, open pleats increases usable surface area for enhanced dust holding capacity and longer service life. 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.
