aFe Magnum FLOW Intake Replacement Air Filter w/ Pro DRY S Media 4 IN F x (7-3/4x6-1/2) - 21-90113

These filters feature three layers of our Pro DRY S oil-free synthetic media to provide a high-flow performance filter with a simplified maintenance routine. The progressive layering provides great filtration efficiency and dust holding capacity. This media is best suited for street and light off-road use. Pro DRY S filters are easily recharged with aFe's POWER CLEANER. aFe POWER performance air filters use a rounded, evenly spaced pleat design which allows for more usable filter surface area, providing increased flow and greater dust holding capacity. These aFe POWER performance air filters are constructed with a polyurethane base and top. Unlike other materials that degrade after repeated heat cycles in an engine bay, polyurethane maintains its original molded shape.
