OK, so I was at the dealer getting first free oil change(2600mi). I asked service advisor if 2006.5 Xb's come from the factory with cabin air filter. He says "Good Question." He asked mechanic who said look behind glove box and see. I did but I can't tell. I see where it goes. I see a white round area and black on top left and right corners. I don't see what would look like filter material. Is it on the inside and therefore I can't see it? Do they come from the factory with them now?
