Snorkel:

Volant cold air snorkels are for more than tackling water crossings. For the serious off-roader, a cold air snorkel, which draws air from an elevated position, is ideal for dry and dusty driving conditions.

By moving the cold air collection point to an elevated position, you eliminate the chance of drawing in warm engine air as well reduce the amount of debris entering the air path while rock crawling or trail driving.
