CAI isn't a TGP term. It's a generic abbreviation for Cold Air Intake. :)

Now going from this 2 a slightly different topic, how much does a CAI really help a turbo car, air is gunna get hot from the turbo and still get colder from the IC.

Air gets sucked by the turbo so fast that I don't know how much heat is transferred during that time. Also, the engine gain more power only because you have colder air, it will gain more power because you have more air. However, because colder air is more (thanks rob) dense, more air can be crammed into the cylinders. The practice of cramming more air into the cylinders is the same reason we have turbos (exhaust gas powered, turbine spun air compressors and superchargers (belt driven ones). Hope this helps.

Cold air is actually denser than warm air. The molecules are closer and when in the cylinders they expand (explode) greater during the combustion process. This is why these cars have additional "punch" in cold weather. The turbo is made of 2 parts, the rear is exhaust driven and the front end is what draws in the cold air to charge the system. It would also help to wrap the IC pipe to the TBI to keep everything cool.

Yup, I understand a CAI helps on a N/A motor, but because we have turbos, I cant see how it would help to have a CAI vs just a big filter directly on the turbo. By the time air passes thru the TB, its already had to go thru the turbo, IC pipeing, the IC, the TB, the plenum, and lower intake manifold before the air actually gets to the engine, is there actually going to be a temp diference in the air if its (lets say: 10 degrees colder before it gets into the turbo?

Here read this article from Gale Banks! Mr. Banks is the supreme leader of all when it comes to turbo-charging or supercharging... 8)

Thanks for the info. Now it all makes sense. I have a CAI on my TGP believe me you can tell the difference.
