About all you could do without going to drastic extremes of hacking sheetmetal for a gaudy snorkel, or hacking up your airbox and losing efficiency , would be to get some PVC pipe that will fit in The flex elbow. Have the PVC pipe fitted to run up and to the passenger side toward the computer box area as high as possible Then, when you need to ford, all you need to do is detach the flex elbow from the airbox and insert the pcv pipe and lay it up in the corner of the engine compartment.
