Pro DRY S Filter Media: 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, while its inverted top makes for more filter surface area, resulting in longer service intervals. This media is best suited for street and light off-road use. Pro DRY S filters are easily recharged with aFe's POWER CLEANER.

Unlike other materials that degrade after repeated heat cycles in an engine bay, polyurethane maintains its original molded shape. Innovative Design: Utilizing the filter's external locking tabs, the filter snaps into most Momentum series housings with zero hardware. This patent pending interface allows for easy filter maintenance and replacement.
