I need to get COLD AIR into my CAI, Any ideas ?

That isn't a cold air intake, it's hot air intake. If someone told you that's a cold air intake, I recommend you not believe anything else they say.

There might be some small power advantage to an authentic CAI on a Prius, but that isn't a CAI by any stretch of the imagination.

 

Yup, totally agree with this.
There’s even a thread on here somewhere about rerouting the air intake so it picks up MORE hot air.

Amazing cars these things are, I’ve had mine for a week and I’m having to learn all sorts of new things!
