OK guys I left something out.
       I plan to do this on my IO 320 next winter.  I was advised to put a
pressure release door on the bottom of my air filter housing.  This door
will open inward by suction pressure should the filter get iced over.
While I have not done this my self, yet, a number of the twins have this
release door and I think it is a good safety feature.
