Don't think so, their own mechanics know very well how to install stuff, as they do it all day.

It's probably for being "bullet-proof" (or was that "idiot"-proof ) for any person that wants to do the changeut by him/herself.
Which in fact is highly recommendable, You simply can't tell exactly when the same cabin filter will need to be exchanged, putting it totally different situations of useage (Well, You could if You installed a pressure gauge measuring dP, but that's another story). So the best is to check on a regular basis and change it when necessary.

Generally an arrow is put on a filter when the filter media has a gradient fibre structure..I have some serious doubt that the OEM media has such a layout.

@Almatti: You're right, Italy is a great country, but...well, You regularly watch the news I suppose.
On 24 and 25.02.13 there will be the national election (parliament+senate)...let's just hope that the most serious and best-qualified people will be voted.
