Oiling the Two Stages: Because the two foam layers separate, oiling and cleaning is a breeze. Pull the red outer foam off the yellow inner core. Oil both layers generously with a quality foam filter oil, massage it deeply into the foam cells, and firmly squeeze out the excess. Never twist or wring the foam like a wet towel, as this will shear the cells and ruin the filter. Let the carrier solvent in the oil flash off in a well-ventilated area for 15 minutes before reassembling and installing.
