Most CAIs are built the same there is no real difference between that and other ones.

Keep in mind that a Cold Air intake is what it is...a tube with a filter. There is nothing magical about them at all. Honestly, you could probably go out back and find a damn pipe, hose clamp on a K&N filter, then shove it in your air box, it may work exactly the same.

Sorry for being off-topic, but

Which is generally better: cai or a high flow intake?
How does the cai cool air? Does it use any form of liquid?

I heard, somewhere, cant remember, that cai uses water to cool air coming in. If the tube leaks, water can be sucked into the engine and wrecks it. Is this true?

Depends on the application - I believe high flow is only really effective when using forced induction or if the motor has a ram air system, so unless you're planning to supercharge/turbo your motor, don't worry about it.

It doesn't actually cool air at all. The whole idea is that the intake is placed away from the engine - normally air going in has been heated by the high temperatures coming from the block, but a CAI helps by sucking the air in from a cooler spot under the hood.

False. As I said previously, CAI systems have no active cooling method. You may be thinking of water cooling, which is quite common and generally reliable.
