So I was out in my garage, looking around at all the crap that I have accumulated, and I had a bit of a laugh when I found a history of what I had in reserve for my 17k mile CBR600RR. I know for sure that I had one of these KN-204 filters on the bike for 3-4k miles, and no issues. This batch was from around 3-4 years ago. I may just hang the K&Ns up on the wall and just keep them around as backups in case someone or I need a fresh filter for some reason.
