It's mainly a safety factor. Often intakes (such as ours) are located near the front of the vehicle to get colder air. This works against us when pushing through water due to the bow wave. The majority of the engine may not be underwater, but the bow wave could engulf the air box.
If you do get a good dunking, replacing some smaller electronic components may not be too expensive or difficult, but bending a rod in the case of water injestion into the intake is very expensive (most likely would be an engine replacement).
There's another benefit when driving in a convoy on a dusty road, you can generally get cleaner air up high. The TECORE guys know how dusty it can get behind another vehicle when driving on the long dirt and gravel tracks.
