If you really believe that some of use here have some 6 month to one year old efficiency tuned filters we'll sell you for our cost and shipping of course. This is the second time I've offered them in a month and no one's jumped at this bargain?
I don't claim anything. Just asking, it is just a question, and looking for a simple answer, not sarcastic comments.
If an air filter gets clogged or loaded up, does it have better efficiency?
If the answer is Yes, than new air filter won't fix it. You need to check if there is a leak in the intake system.
Also, I do not see anything wrong with the UOA. OP run the oil 2.5x more than universal averages. Wear metals are slightly higher than averages, nothing to worry about. I wish we were able to see TBN, but I guess you need to shorten the OCI. I'd try 10-12k mile OCI next time and see if it makes things better.
