So here are pic's of the K&N HP-3002 oil filter with the break in oil. Maybe an hours run time on it. In the bottom there was a small amount of metal I could feel like fine sane paper between my thumb and index finger. All the flaps pretty much looked the same. Maybe I need to look on the inside of them too? Oil was clean in clear pan I drained into. This is the first time I've ever cut into one before.
