Thanks for posting the TSB. Being a new owner of a Genesis 3.8L, based on my reading, the tsb may have been more for older Hyundai's and as posted for a knocking "noise".
What I've seen of the Hyundai OEM canister filters, they are solid filter construction. That said, I wouldn't be afraid to try a Pure One and/or Wix, and see how they perform. No difference, I'd continue to use them if they are better value.
I can say the new Hyundai cartridge filters, though relatively expensive, are nothing more than ecore type construction. In other words, nothing special, imo.
