I recently replaced my OEM filter with a new K&N filter. It was only after I threw my old filter out that I read the small scrap of paper that came with the K&N informing me that I need to remove the rubber gasket from the old filter and place it around the K&N. So now I am looking for a replacement rubber gasket. If all else fails I guess I will buy a new OEM filter just for the gasket, but I thought I would ask here first. Does anyone have an old OEM air filter that still has the rubber gasket? If so, please PM me... I would like to buy it from you.
