This is the filter from my first OCI on the CATERHAM blend, UOA here. Nothing out of the ordinary, typical Wix. Maybe less wavy than the last one I used. You can see some grit in the bottom of the can, I don't think it is from cutting the can (I use a rotary tool) as the two filters I opened from my Son's Mazda did not have anything like this in the bottom. This UOA had elevated lead, nothing sparkly in the bottom of the pleats however. spots in bottom of can appeared to be more like maybe carbon.
