Thanks!

Why is there no air filter? What does blowing snow have to do with
that?
The filters catch dust and crud in the air, and that can happen in
winter as well as other times of the year (though dirt dust would be
pretty well subdued, I would imagine ;) )

I can't recall ANY engine without an air filter.
