Oil filter question.

so i had motortrend on this morning and the oil filter episode was on.

they like the K&N gold. they say its 10 micron. I can't find the gold anywhere. the HP looks like it and is what comes up in a search. the HP says its 30 micron though.

they did cut them all apart and showed the difference inside. the fram racing looked much better then the other frams inside. wix looked good and performed well too.. the K&N gold was the smallest micron, was built out of thicker metal and preformed well too..

anyway here are their results.
