today at work, out of boredom, i decided to cut open one of my old R6 oil filters. when something is oem, i usually expect it to be top notch quality. to my surprise, this filter had some sort of hard object for filtration. i have no idea what this is made of. it doesn't look like that great of a filter considering how much i pay for it. i guess i can't just judge it right off the bat though without cutting open any other filters. i just find it odd, it doesn't filter anything like a car filter (well, it does only to an extent) opinions? anyone else cut open filters before? k&n or anything?
