Performance Overview

The aFe Power Magnum FLOW Pro 5R OE Replacement Air Filter is designed to enhance airflow and filtration, delivering increased horsepower, improved throttle response, and long-term engine protection. Built for high-performance applications, this premium oiled filter maximizes airflow, ensuring your engine receives clean, unrestricted air for optimal combustion. At the heart of this filter is five-layer progressively finer cotton gauze media, engineered to trap contaminants while maintaining exceptional airflow. The deep rounded pleat design expands the surface area, allowing for greater dust-holding capacity and extended service intervals. This ensures the filter continues performing at peak efficiency, even in demanding conditions. Constructed with a durable polyurethane frame, the Magnum FLOW Pro 5R offers a precise, factory-style fit while withstanding repeated exposure to heat and pressure. Its pliable sealing surface conforms to the airbox housing, eliminating the need for gaskets or sealants and providing a leak-free installation. Fully washable and reusable, this filter is built for longevity, requiring only periodic maintenance using aFe's POWER CLEANER and blue air filter oil. For those seeking maximum airflow, superior filtration, and long-lasting durability, the aFe Power Magnum FLOW Pro 5R OE Replacement Air Filter is the ultimate upgrade, delivering uncompromising performance and reliable engine protection.
