Here are some pics I found while Googling.....

This is what it's supposed to look like from the box. Info I found says that the correct size for my model Outback (MY99) is 33-2154.

This is what an Outback's filter box looks like.

Apparently inside the K&N packaging is this Gucci looking sticker which is supposed to remind people not to throw the K&N filter away.
Any info would be appreciated.
