They fit and they work!
Size: 72880-FL00A
We purchased these a couple of months ago, and we installed one in our 2024 Subaru Outback Limited XT right away. We just wanted to use it for awhile before we left a review. First, it fit perfectly in our Outback. There is a very faintly printed arrow on one side showing which way the airflow is supposed to go when installing it. Pay attention to that arrow. Second, these air filters really work. They have even filtered out bad smells and light smoke we have had to drive through. They are easy enough to replace yourself, and you can save some serious money over having a mechanic do it. If you can work a screwdriver, you can probably replace a car's air filter yourself. At least that's been our experience with all the different cars we have owned. We are very satisfied with these filters and would recommend them to others.
