I have an AEM CAI, and yes It comes with a kit that I didn't use. It requires drilling, wire extensions, and all kind of B.S. As of right now I have no water sprayers, but check this out, you could buy the water bottle that comes molded for the intake already from DC Sports ( I asked) and I think it's like 20 bucks or something, its what Im planing on doing, and It will save you a headache.
