During cold weather operations, something that I have seen on-highway trucks do (especially snowplow trucks) is redivert the intake air system such that air is taken from under the hood. I believe that the snowplow folks call this device a "snow valve". It seems to serve two purposes:
1. Keep snow from plugging an exterior air intake (not uncommon with the amount of snow blowing around the front of a plow truck)
2. Increase the intake air temperature for improved combustion (excessive cold air intake temp. leads to white smoke production)
Anybody try this trick with a tractor? I could easily remove an air intake hose from upstream of my TC21D's air cleaner and get the same benefits... I'm just uncertain if I really need to...
