Product Description

The aFe 21-90038 Magnum FLOW Pro DRY S Universal Air Filter is a high-flow, oil-free performance filter engineered to significantly improve airflow and filtration efficiency in compatible aftermarket intake systems with a ~6" flange connection. Utilizing Pro DRY S synthetic media, this air filter balances excellent dust capture with superior airflow performance, helping maximize throttle response and potential horsepower gains over restrictive stock paper filters. Its washable and reusable design extends service intervals and reduces long-term maintenance costs.

Constructed with a pliable polyurethane flange with integrated bump seals and a durable top and base, the 21-90038 creates a secure, leak-free fit in many performance intake openings. The conical shape and deep, evenly spaced pleats increase usable surface area, improving dust holding capacity and filter life. 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.
