hahaha doesn't sound as cool.

There are little plugs you can get you fit the TB to block it, It doesn't work as well, But it is removable. Nice if you live in a cold climate and actually need the TB heated in the winter.

I simply removed the UIM from the LIM and drilled and tapped the holes with a 1/2"-13 plug. Has been done on S2'*, also works on L27'*.

IMO the best thing to do would be to get a phelonic spacer between the UIM and LIM to cool the UIM off. YOu dont want your TB freezing in the winter do you? I doubt you will notice much of a difference.

Well my upper doesnt even feel hot, its my TB that is on fire. Its ok though I just thought itd be a cool idea.

What do you mean by throttlebody freezing in the winter? <--I'm just not sure what you mean

I dont know either, maybe the little plate will get stuck? Oh and what does it mean when a slight bit of smoke comes out of the intake when you shut off the car?

I'd say it has something to do with your EGR valve. Probably, it has stuck itself open, but I've never heard of this happening to the point where noticeable amounts of smoke came up the intake.

If you're in a cold climate you need the TB hot to preheat the air to make the engine run nice. That'* why the removable plugs are available.

Note CAI stands for Cold Air Induction, not intake.

And everytime the intake charge passes through another part it only gets hotter and hotter..
