FYI, I made a filter holder and am using house filters cut down to size in the filtering system. Didn't take too long to figure out and costs a lot less than the OEM solution (the best home filters are ~20$, I can make 4-6 car filters out of them
I posted the dimensions in a previous post: http://forums.nasioc.com/forums/show...hreadid=543945
. You can see pictures of the filter holder on the Montreal Subaru Club's web forum: http://www.montreal-subaru-club.com/...247&highlight=
And I, too, was amazed at the amount of dead leaves and such in the system. Also, using a rough filter for less than one week produced a lot of dirt to be trapped...
