The aFe Magnum FLOW Universal Air Filter with part number AFE21-91134 offers a high-performance, oil-free filtration solution designed for maximum airflow and durability. Constructed with three layers of progressively finer mesh synthetic media between a 100% polyurethane top and base, this filter ensures efficient dust trapping while maintaining excellent airflow for optimal engine performance.

The pliable polyurethane flange with integrated bumps guarantees a tight, leak-proof seal over the filter*s lifespan, ensuring that unfiltered air does not bypass the media and compromise engine performance. With a filter efficiency of 99.2%, this filter effectively captures a wide range of airborne contaminants to protect your engine components. Designed for ease of maintenance, the Magnum FLOW filter is ideal for those seeking reliable, high-flow filtration that combines performance with convenience. Its robust construction and precise fit make it suitable for a variety of automotive applications where high airflow and filtration efficiency are critical.
