I have both sets. Simply stick a cup magnet to the oil filter, preferably the flat end opposite where you screw it in, and you're set. Pull it off at the next oil change, they're reusable.
This will skew your oil analysis, but whatever, it extends the engine life.
And have you run UOA both without and with using these magnets to see how it skews the results?
I tried this approach on the outside of the oil filters for my car (because I was extending the OCI by 4X over the manufacturer's recommendation), but when I cut open the filters (with the magnets still attached) I found nothing collected on the inside of the can.
After the run in period magnets attract very little and what they do will be caught by the paper filter. The main wearing items are non magnetic.
