I don't see anything wrong with OP hording metal wire backed synthetic filters since its long confirmed here they're no longer being in production. If you see his channel, he's quite the car enthusiast like many of us here and wants the best protection possible for his investments. Also gives a piece of mind you don't have to play the game of shopping roulette when in the market for a new filter when that oil change comes up.
I recently did the same as well as I want the best protection for me and my family fleet of vehicles to use the filter that has been verified by a third party filtration laboratory test posted in this forum years ago. Hopefully when my filter supply is exhausted many years from now we get something better than the FRAM Ultra/Endurance. Filtration technology has come a long way 10 years ago.
