is it safe...? seems like all I ever see is a cold air box never a cai on a turbo?

i think he means putting the filter directly on the turbo.

i see a lot of people do it but if you can put a pipe between that would probably be better.

It's fine, denser air is always better.

Why wouldn't it be? The car came with one stock.

There seems be be mass ignorance about this topic. A "cold air box" and a "cold air intake" are the same thing. It's not one part, like a pipe or a heat shield; it's a complete system that ensures only outside air enters the intake and not engine bay air.

Plenty of Turbo owners have a CAI of some kind. Maybe you just haven't seen many Turbos.

This whole statement could not be more wrong. If the air's colder when it enters the intake, it'll be colder when it gets to the engine. This is just common sense.

A short peice of pipe is not a CAI! You're talking about the TID, which is a completely different topic.

Well yeah but engine bay temp. will have some effect on IAT. If the ECT is 212 degrees and the intake is 60 obviously the heat will transfer into the intake ducting and raise the IAT. So saying that the previous statement is completely and utterly false is not completely true either. However it would be cooler (like you said) than with a stock airbox...

The previous statement is utterly false. You are going to get heat transfer into the intake air no matter what temperature it is when it enters the intake tract, but if you start with colder air, you will a colder charge throughout the system.

yeah exactly what I said but just a little bit more abrasive....

Nobody ever said it wouldn't, but that doesn't change the simple fact that if the air's colder when it enters the intake, it'll be colder when it gets to the engine, no matter what happens to it along the way.

Let me make it clearer. He said "It would be worthless as for the cold air part because the turbo will heat it up but it should help flow a little better but it would be just a 45 degree bend piece of pipe.", which is referring to the TID, which has nothing to do with a CAI.

I never said that...
