air filter, bought fram, it looks like an airfilter (panel car engine filter) with smaller mesh. original is different so it doesn't fit that well. The instructions are in the owner's manual, but instead of the clips on the wiper, like the instructions say there is, mine was on a taper, and i had to use a small gear puller on it to get it off. Not too hard to do, but you need Torx wrenches, maybe a gear puller, and have to remove about 10 screws. harder than engine air filter, but not very hard.
