Does the term "red rubber ball" have any help here?

Hello everyone. It's getting a little chilly around here now; I have seen
the "ventubes" that are being sold for $75 apiece. Has anyone simply
taped over the inlet in the wing root? I was thinking of giving this a
try, seeing that there is no real need for cold air ventilation at this
time of year.
