Throttle Body Coolant Line bypass - I dont know much about why the throttle body needs a coolant line, or doens't need one. I have heard some members do a bypass and wonder why?

Few questions, maybe some of the experienced tuners out there will chime in...

1 - why bypass the tb coolant line, so the tb gets hotter - whats the purpose?
2 - would a mod like this provide gains on a n/a engine?
3 - any negative effects from bypassing?

 

1:its to warm up the in coming air on cold start up's
2: not really pretty must the same effects as a CAI
3: theres not really any negative effects excpt more fuel useage when the engine is still cold...

 

thanks!!!!!!!!!
I was suspecting as much, but wanted confirmation
