Ugh, the air filters are rare. They were used on 70s-early 80s Porsche 911s, so you can still get a few but yeah. WIX has long stopped making them.
Oreilly only shows the KN filter for an 83 Porsche 911, $90. The Fram one is around $20 online. I found some other off brand ones but they are about $40.
