I recently replaced my stock filter with a K&N replacement. Upon opening the filter case I noticed not one but TWO filters. One that was wire meshed and practically stuck to the top of the air filter housing. The other was a white cheap paper filter. So I ripped out the wire mesh filter, and threw the paper filter and repalced the whole setup with just the K&N, which seemed to fit fine. Did I do anything wrong? Tell me the part I threw out wasn't critical to the air flow intake?!!!
