This article explains the function and importance of snorkels on vehicles, particularly for off-road and flooded-road driving. Snorkels protect vehicle engines from water and dust, ensuring safe operation in challenging conditions.

• A snorkel allows a vehicle's engine to take in clean, fresh air even when crossing rivers or driving through flooded roads.
• Snorkels are crucial for vehicles operating in harsh conditions like heavy rains, dusty roads, or deserts.
• The main purpose of a snorkel is to prevent expensive engine damage caused by water entering the air intake.
• While some vehicles, primarily city cars, lack snorkels, many four-wheel drives and heavy-duty trucks are equipped with them, either from the factory or as an aftermarket addition.
