On the OEM intake it is the cube that is attached to the intake tube, near the MAF sensor. It has two vacuum hoses and a connector going to it. I would start there and work in both directions checking the vacuum hoses.
Water wouldn't cause the 0456 unless it's water getting into fuel overflow and plugging up the charcoal canister. There was a TSB on that issue on 07's, but that was fixed by 08.
