As of right now only the 15208AA160 is no longer going to be available in the states. Once supplies are drawn down there will no more from what I have been told. So here at Somerset Subaru we prepared to get as many as possible from a couple local dealers that had a couple to many as we sell a ton of these filters. I have 16 cases available.
The 15208AA160 is superseding to a 15208AA15A which is basically just a taller version of the old 12A. It is a blue filter that is made in the USA. The 160 and 130 come from Japan and the 130 will not fit the Impreza. So when your local dealer runs out you will know where to get them well until I run out .
