Here is a couple of pics of the hose route i used. I did bend the hard tube at heater line so the hose would arch nicely under the AC.

PVC will deform from heat. I had a PVC tee on mine and it bent into a U shape, I decided to remove it incase it got brittle. I just went with a new hose, I bought five feet of heater hose and new clamps. You can then route the hose much nicer. This makes taking the TB off very easy. For new people doing this, look at the clamp before buying it, some really suck! Use a quality clamp.

Such conditions that no C4 owner would risk driving their car in, how often do you drive in sub-zero weather when there isnt snow on the ground?

I agree, you would probably have to live in the North Pole for the throttly body to stick from cold weather. The coolant runs through the TB to warm it up during very cold weather. There is no performance gain from this mod, only the mind set that the TB doesn't heat the incoming air as much.

Iceing can occur at 32 to 38 degrees while driving at highway speed. It will melt by the time you stop the car and open the hood to see why your car is not running right. Very unusual but can happen if under the right conditions. I wouldn't worry about it unless it is a daily driver.

Did it improve performance? Hard to tell.

On the LT-1s you just run the hose from the radiator T directly to the steel heater line under the passenger fuel rail cover. No coupling, no extra hose.
The air isn't going to be any cooler going through the TB at that velocity but the temps under the hood are lowered a little, and every bit helps I guess. The TB and plenum are cool to the touch afterward vs. red hot.
And it's free!

You can't see it which is better than seeing it lying over your valve covers.
Here is a couple of pics of the hose route i used. I did bend the hard tube at heater line so the hose would arch nicely under the AC.
