Magnum FLOW Intake Repla cement Air Filter

The Magnum FLOW Intake Replacement Air Filter from AFE POWER is engineered for mechanics and enthusiasts who demand measurable intake flow gains without sacrificing engine protection. This reusable cotton filter element replaces stock restrictive air boxes, making it ideal for naturally aspirated builds, daily drivers seeking better throttle response, and tuned vehicles where intake velocity matters. Unlike disposable paper filters, the Magnum FLOW design allows sustained performance while remaining cleanable and serviceable—reducing long-term ownership costs for serious automotive projects.

The conical filter geometry—featuring a 5-inch base diameter tapering to a 3.5-inch top with 7 inches of height—maximizes surface area for unrestricted airflow while maintaining fine filtration. The reusable oiled cotton media captures contaminants more efficiently than paper equivalents, with the blue outer coating indicating proper saturation for optimal filtering performance. The clamp-on mounting with a 3.5-inch flange delivers tool-free installation on compatible intake manifolds, and the pair configuration gives you coverage for dual-carb setups or future projects. This universal design integrates with most classic and modern intake systems where bolt-on air filters are the primary restriction point.

Technicians installing performance intakes, custom engine builds, or high-rpm applications benefit most from the Magnum FLOW's ability to flow cooler, denser charge air into the cylinder head. The reusable media means periodic cleaning with AFE's proprietary cleaner—not replacement every season—making it cost-effective for active enthusiasts. Ensure your intake tube diameter and clamp configuration match the 5-inch base and 3.5-inch flange measurements before purchase; verify your manifold's intake boot compatibility for proper fitment.
