What do you need "More room for you CAI"? All you need is a really long ground and positive because you'll need to run a ground to the engine block to keep noise out of your system, the best bet is to just run some two gauge from the battery to the stock connectors, You'll get some serious IR drop for cables that long so big gauge is necessary. Don't be surprised if you induce a lot of noise in your stereo. It's pretty easy, a battery relocation kit is the easiest, they usually come with wires with one end that looks like a battery post so you can just tighten the old clamps to it. Then the battery tray and some bolts, you'll need to find a place to drill. If you put it in your trunk, I highly suggest dropping your tank before you start drilling. I had the battery in my prelude in back, but it was a 13lb race battery. If you don't have anything other than looks to gain moving it, why not just leave it alone?
