The CAI/WAI air does not provide any antifreeze cooling at all..
So if you live where it seldom gets cold, by-passing the TB should let the intake air remain the same temp (supposably).
But if you live where it get very cold, by-passing the TB could cause freezing of the TB and sticking butterfly.
Ive seen a few bypassed TBs do just fine in coldest winter weather. You just must warmup the car before driving in very cold weather.
Well yes I know that it keeps freezing of TB away, but in my personal tests, I noticed after the TB heater bypass, my water temps stayed in 190's in September, before they would be in the 180's
I posted about it here
