So the part number for the Frams (Endurance and Ultra) for a 03 Legacy were 3593A. Now the part number is 9688. These 9688’s are shorter and wider than the Subaru OEM filters. I don’t know if they are shorter and wider than the Frams 3593A. But being wider than the OEM’s Will there be a problem with fit?That's the one. $12.97 for a much better filter than OEM at only $2.97 less, seems like an easy decision. Being honest, I just don't get excited about OEM filters and oil. There are such better options out there!
