I'll probably stick with the stock, OEM air filter for the Camry, though I'll likely change out the stock oil filter for a Mobil 1 or Amsoil model--probably the Amsoil because the Mobil oil filter has rough threads, not as smooth as I had expected. I think the Amsoil oil filter is model Ea010 or Ea0010 IIRC.
So I don't lose the info, I'm posting the specs for the stock Toyota OEM air filter:
Air Filter for 4-cylinder LE:
Model = ACV30
Part number = 17801-0H010
Production date = 0107-0602
Cost is $17 online from the Toyota parts web site ToyotaPartsAndService.com , which also provided the specs listed above.
