I asked my tuner (Chris @ EFI Logics) No gains whatsoever from this mod...
Added note to UK-Wagon, he's absolutely correct. I was born and raised in Alaska and unless you're North of the Arctic Circle then no TB is gonna stick due to weather outside. Where that notion came from is beyond me but people need to go back and learn about thermal dynamics and condensation properties with metals. :-/
Does it REALLY assist w/cold start ups? Maybe, but I don't see how, it'll heat up the intake charge about 3 minutes faster in weather below 32*(0*C)...so really? sticking? Cold start up? I don't buy it, but the idea is sound so why not just leave it alone, it doesn't hurt or gain you anything by just not touching it.
