If you put in a filter or a screen, you must put in some sort of by-pass in case it gets clogged with snow.

One situation that I can think of, that is very likely to occur would be flying into a swarm of bugs. Even a coarse screen such as Al has installed could
easily become clogged with dead bugs choking off all intake air and causing the engine to stop running. That swarm of bugs without the screen would in all likelyhood be ingested and spit out through the exhaust without so much as a hiccup by the engine. Just playing devils advocate. :o)

topic to me as I can't think of any reason to not protect the engine
with a filter.
