Every filter manufacturer has their own codes, so it's best to go to a parts store (Pep Boys or Autozone) and look it up--they usually have a manual. If you want to be absolutely sure you're getting a good/correct filter, just get one at the dealer. They're a cuppla bucks more but at least you know Toyota backs them.
Best of luck!
