Yes I saw it in the International Motorcycle Show a couple of years ago in K&N's booth but it doesn't tell us jack. What it shown was that K&N has more air passing thru comparing to other filters but what it doesn't tell us is how much more dirt K&N let passed.
True, It didnt tell that. I thought the material K & N and Cool Blue uses traps more dirt than a stock paper one??? Wasnt it like 30 microns or something like that.
