This is aFe's Magnum FLOW OE Replacement air filter with Pro DRY S media and a foam pre-filter, a drop-in flat panel for the factory airbox on 2003-2026 Dodge and Ram trucks with the 5.9L and 6.7L Cummins inline-six diesel. Pro DRY S is three layers of oil-free synthetic media: it is washable and reusable, and unlike an oiled cotton-gauze filter it needs no oil at service time, so there is nothing to over-oil onto a mass airflow sensor. It is recharged with aFe's POWER CLEANER and air-dried.
What separates this part number from aFe's other Cummins replacement filters is the pre-filter and the frame. A 1/2 inch open-cell polyurethane foam pre-filter, held by a removable ABS retainer, catches large debris before it reaches the media, which is worth having if the truck works in dust; it washes and reuses the same way the filter does. The filter itself carries a full 360-degree polyurethane frame rather than a partial one, with rounded, evenly spaced deep pleats for surface area and dust-holding capacity, and an integrated progressive bump seal that conforms to the airbox without gaskets or sealant. It drops straight into the factory housing - no modification, no tune. aFe states this product does not require a CARB EO number. Compare with part number 31-80102, which is the inverted (IRF) filter for this platform.
