The aFe POWER Magnum FLOW Pro DRY S Air Filter (part number 21-91155) is a universal-fit unit measuring 4in F x 6in B x 4in T Universal.
This filter features three layers of oil-free synthetic media and requires no oil during maintenance to provide maximum convenience. Its 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.This aFe POWER performance air filter is constructed with a polyurethane base and top. This construction allows for a proper factory style fit with excellent filter strength. Its inverted top makes for more filter surface area, resulting in longer service intervals. Utilizing the filter's retention groove, the filter locks into most Stage-2 housings with zero hardware. This simple design allows for easy filter maintenance and replacement.
