It and a "warm air intake" modification did wonders
durring a winter trip through the norther states.
But I don't use it much here at home as it's never cold enough.
The Prius on the otherhand is a whole different beast, and
while I suspect that similar benefits might come from the
radiator and/or warm air mod I can't speak from experience.
In the Insight the radiator blocking resulted in about 3
degrees warmer air intake temp per 1/3rd blockage. The
warm air modification which draws intake air from either
the catalitic converter or the top/rear of the engine
compartment resulted in an additional 10 degree F rise.
Notice: Never block the entire radiator!
ps. Why does it help?
Engine compartment warms up faster, warm engine compartment air
stays under the hood longer, less heat disipated by radiator,
better air/fuel mixing, more complete combustion? I could be wrong.
