Hello people! Have a question: I changed the pollen filter today with my 05 Smart CDI – well, there was no one in it before, now already 😉 My question: He is now as said one inside, but am not quite sure if I have installed it properly. I gave the darker side in the direction of travel to the front, so I pushed the frame with the foam borders back into the box. Is it possible that he is sitting there diagonally in it, say on the driver’s side a little further behind and should you feel there next to it a free air channel? Besides, I gave it up at the edge, so with the grooves from top to bottom – should be no matter, because square, or crazy I am there? Thank you for your opinions/help! lg Christian
