Some snorkels move the point where the air is taken in, to as high as the roof.
This page shows an inexpensive approach I took to attempt to reduce the possibility of water intake into my engine. If you choose to do the same thing, you do so at your own risk . This information is not intended to suggest that water can be prevented from being taken into the engine, thereby preventing engine damage. Installation of this snorkel may reduce the amount of water intake, not prevent it. If you install this snorkel, do not assume that you are any more impervious to engine damage than without it, by driving in deeper water than you would have without the snorkel.
