There is a book listing at walmart but only for those behind the desk and apparently the boy couldnt read. Because l know he was wrong l just cant remember what was the right one. And no where in my question do l recall saying there wasnt a book. l usually go to an auto parts store however money is tight. You're obviously a rude and uneducated person.
And thank you to everyone else who atleast tried to answer the question without being rude.
its a 98...

F-walmart go to a auto prts store..and r u telling me theres no book/listing at Fing walmart? l do not believe you

There is a Fram book there in the filter section that cross references all the sizes and matches them to your car. That will be your best source of information.

When ever you go to buy a filter they have a book hanging by them so you can look up your make and model by the year. That way you do not have to depend on some erroneous info.

You can look it up on Fram is website. You did not say what year vehicle, or what filter, so l do not have enough information to do it for you.

More than likely it is a Fram PH3593. Most all Subarus use that one.

buy a k&n

A 98 Legacy or Impreza with a non turbo (2.2 or 2.5 SOHC) engine should use Fram # PH3593A or equivalent..
