Guys,
Someone sent this to me and I don't have a clue - anyone else out there know what's up?

I have no idea where this thing goes, and have never tooled around under my dash...Hi, I have a little problem with a cabin air filter install, thought you might be able to shed some light on it? I own a MY2001 Impreza RS and recently purchased a cabin filter to replace the old one. The instructions say that the filter goes behind the glove box. So, I removed the glove box and do not see anything remotely larger enough to fit this filter into(it's
quite large 10'' by 8"). They say in the instructions that there is a filter cover to remove but I don't see one? Is it possible there is another place to install the filter, may under the driver's side, or could it be possible the dealer sold me the wrong filter or something, possibly for a 2002? I will continue to search for other install instructions, but if you have any
info it's very appreciated.
