What does this "winter front" do?
Is it for increased perfomance?, comfort?, or just cosmetically cool?
I have one. When it's cold enough to really need it, I might just stay home. You remove it above 20F. I will fly down to 0 F, after preheating with or without it. My cabin temps don't seem to be affected at all. But I will admit that new one looks nice on Brenda's plane.
