I don't see that anyone has answered this, but WIX filter WP 10176 was added to their line for Tesla in Sept 2015. It's about $25 and looks somewhat beefier than the OEM filter. WIX is a high quality line, so no worries there. It takes very little time and no tools to do-release the center panel covering the rear of the frunk at the windshield, work it back toward the windshield to wiggle it out, remove the snap in cover from the passenger side firewall, and take the old filter out. Note that the airflow arrow is pointing UP when you put the new one in. That's it. Put it all back together noting that the cover has a couple of molded clips to engage at the windshield side. Finally, something I can do on my wife's car besides add windshield washer!
