Throttle Body bypass???

[Vettster]

This mod has been around awhile. I did it to my Corvette back in 1996.
The coolant is run thru the throttle body to prevent it from icing up.
In theory, it also heats up the air/fuel charge and make it less dense.
Fine mod if you live in a warm(er) area. I don't think I'd try it in Alaska though.
