I would leave it on. I left it on my Injen intake. I'm not sure what purpose it serves though. What CAI are you putting on? It should have came with a tube for it. Or modify your pipe. Or put a mini air filter on the box.

It's just an emissions device. Sorry to be late on the help here, if you had posted this in the S13 thread I would have caught is sooner.
The AIV doesn't matter. You can remove the whole box, valve, and piping as I did, but you need to weld a flange on your headers.
If I were you, I would just hack off the hose going to the black charcoal box. This will not affect your car's performance.
