now i know most here have the RMR intake with the K&N cone filter or the RRM with its filter.well...i know after a while with mine i have where the air comes from the factory scoop there is a nice lil black dot(well...not really small)now mine has gotten big due to my custom dual duct induction.but now it is clean like new due to the mighty price of $9.95 for the K&N filter recharge kit.Simple , quick , cheap , and affective.no more ugly black dot on my nice filter.i highly recomend this product...shoots...$9.95(at autozone)beats buying a new filter for $49.95

 

Thanks for the info, Troie. I'll do that when mine gets dirtier.
