Product Details
Maximize airflow and maintain excellent engine protection with the aFe Power Magnum FLOW Pro DRY S Performance Air Filter. Designed for compatible aFe Power cold air intake systems and custom intake applications, this high-flow, inverted conical air filter delivers improved airflow, dependable filtration, and convenient maintenance without the need for filter oil.
Featuring three layers of progressively finer synthetic filter media, the Pro DRY S air filter is engineered to capture harmful airborne contaminants while allowing increased airflow compared to restrictive factory-style paper filters. Its tall, evenly spaced pleats provide additional filtration surface area and excellent dust-holding capacity, helping maintain consistent performance between cleaning intervals.
The durable polyurethane top and base provide long-lasting structural support, while the flexible mounting flange with an integrated bump seal helps create a secure connection to the intake tube. Unlike traditional oiled performance filters, the Pro DRY S media is completely oil-free and can be washed and reused, making routine maintenance quick and convenient.
Whether you're replacing a worn filter on an existing aFe intake system or building a custom air intake setup, the Magnum FLOW Pro DRY S offers an excellent balance of airflow, filtration efficiency, and everyday reliability.
