Well the opening on the airbox is on the front.... So I would think maybe fiber glassing the hole over, and then cut a new one on the side and run pvc along the fender towards the back, the have it turn out, cut a hole in the back of the fender and then run it up the cab pillar to the top. And if you do plan on doing deep water crossings, you should try to water proof alot of the electrical systems under the hood.
