Well if it's gonna be a PITA I'm not going to bother. I thought it was a fairly simple thing but I've never done it before, that's why I'm asking

It looks like it's more trouble than it's worth, so I'll probably just leave it alone.
As far as the "more room for the CAI" comment, it's because I made my own CAI and the filter is a little on the huge side. I figured if I could move the battery out of the way it would allow more/better airflow to the filter since it's pretty much pinned between the hood and the battery
