Improved Water Wading Ability: The primary function of a snorkel is to raise the air intake point of the vehicle's engine to a higher position, usually above the roofline. This helps prevent water from entering the engine's intake system during water crossings, allowing the vehicle to ford deeper streams and rivers safely.
Dust and Debris Protection: In addition to water, a snorkel can also help prevent dust, dirt, and debris from entering the engine's intake system, especially in dusty or sandy off-road environments.
Enhanced Airflow: Snorkels often feature a larger diameter intake duct compared to the factory air intake, which can improve airflow to the engine.
