Construction & Design

The Magnum FLOW OE Replacement Air Filter features a robust construction combining durability with high performance. Its frame is molded from 100% polyurethane, providing a flexible yet sturdy structure that resists cracking and maintains a secure seal against the airbox. This prevents unfiltered air from entering the engine, protecting vital components.

The filter media is crafted from Pro DRY S synthetic material composed of three layers of mesh with progressively finer fibers. This layered design efficiently captures contaminants while allowing increased airflow compared to traditional paper filters. The tall pleat configuration increases surface area, enhancing dust capacity and extending the time between cleanings. A metal support ring embedded within the urethane seal adds structural integrity and ensures consistent sealing performance throughout the filter’s lifespan.
