Well, they always were a little off...
*ETA*
By the way, your reply of "every Subaru" struck me as odd, what in this day of replaceable conveniences and over-zealous liability attorneys just waiting for Big Car to make even a single misstep. If I were a vehicle mfg I wouldn't want the liability of a regularly serviced part so maintenance intensive as an oiled element air filter. That is, except on some dedicated performance models where the owners would likely know how to care for them properly. So I looked. I found lots of stuff on the web about Subaru air filters. I only found a few references to an oil-element filter. Very few. So I challenge your assertion that every Subaru has an oiled element air filter. From what I can see all but one or two performance models have a garden variety replaceable paper element.

oh, we got our wires crossed.
that's an oiled filter, it's still
disposable. and it looks like the turbos take dry filters.
so not all, anymore. after i got my K&N i kinda stopped looking at subaru filters, don't really have any need for them anymore.
