If water is flowing at any decent rate you will be in the shite long before the depth of it reaches your airbox. Still water I'll do windscreen deep ..................... running water nothing much deeper than probably mid way up the wheels. Weight of a car against a volume of water = massive fail 8.( Get into that situation and the only thing a snorkel may help do is see where you car ends up .................. if your lucky enough to get out of it that is.
