You may need to richen the engine up a little in the cooler months. Other than being a little more difficult to start, they should work OK. That being said, I've never had occasion to fly in temps much colder than those you mentioned. The guys up in the northern latitudes might have more input.

Airplanes generally don't use air filters. I can see how really dusty runways might be an issue but the air where they fly is generally OK. I also wonder if airflow from the prop helps in some way? Regardless, I've pulled some of my engines apart just to have a look and I've never seen any serious signs of abrasive ingestion.
