The aFe MagnumFLOW HD Pro 10R air filter is designed for high-performance intake systems that require strong airflow, efficient filtration, and durable construction. Its 360-degree radial-flow design supports airflow up to 1,000 CFM while the 10-layer progressive cotton gauze media delivers 99.47% cumulative filtration efficiency. The oiled media helps capture harmful contaminants before they reach the engine, supporting reliable intake system performance.

A patent-pending air filter-to-housing interface allows the filter to use a large filtration area while improving available air volume and simplifying installation. The filter is enclosed in reinforced metal for added structural strength, helping resist collapse under demanding operating conditions. This replacement filter is intended for compatible aFe MagnumFLOW HD intake systems and uses a Pro 10R oval configuration.
