I come from the mountain sled side and yes I have run the venting in that area for clutch cooling and have seen it completely covered in snow. Even though I now have the 22 XRS it is still an off trail machine so that is why I made the comment.think about it a little and examine .... it's not only the surface, but above all that the path that the air has to travel is reduced by more than half, less 90 ° corner which is very restrictive as d origin, ram air effects (forced air induction). only advantages.
more over when did you see this part your snowmobiles filled with snow?? never in trail condition. off-piste its something else, but this piece isn't dedicated to that application either.
