Product Description

The aFe 21-91046 Magnum FLOW Pro DRY S Universal Air Filter is a high-flow performance air filter engineered to significantly improve airflow and filtration efficiency in compatible aftermarket intake systems featuring a ~6" inlet flange. This oil-free filter uses advanced Pro DRY S synthetic media with three layers of progressively finer mesh, delivering excellent airflow while effectively capturing dust and contaminants for enhanced engine breathing and throttle response compared with restrictive stock paper filters. Its washable and reusable design helps lower long-term maintenance costs and simplifies servicing. 

Constructed with a pliable polyurethane flange with integrated bump seals and a robust polyurethane top and base, the 21-91046 creates a secure, leak-free seal when clamped into performance intake openings. The inverted conical shape and deep, open pleats increase usable surface area, boosting dust holding capacity and extending service intervals. Because this part is a universal filter element rather than vehicle-specific, always verify that the filter's flange size and shape match your intake system before installation for proper fit and performance.
