What is the purpose of a snorkel on a car?

The main purpose of a snorkel is access to clean air. Most people associate the snorkel with water crossings, as it prevents water from flooding through the vehicle’s airbox and into the engine, potentially causing electrical and mechanical damage.

A snorkel on a car serves a specific and critical purpose in challenging off-road and adventurous driving scenarios. Its primary function is to modify the vehicle’s air intake system, raising the point at which air is drawn into the engine. Here are the key purposes of a snorkel on a car:

Water Crossing: One of the primary reasons for fitting a snorkel is to enable the vehicle to safely cross bodies of water without the risk of water entering the engine’s intake system. By elevating the air intake point, often to roof level or higher, the engine can continue to receive clean and dry air even when the vehicle is submerged in deep water.

Dusty Environments: Snorkels are also beneficial in dusty or dirty off-road environments. By drawing in air from an elevated position, they reduce the risk of the air filter clogging with dirt and debris. This helps maintain optimal engine performance and extends the life of the air filter.

Improved Engine Performance: In some situations, a snorkel can enhance engine performance by providing a consistent and cooler air supply. This is particularly useful when driving in hot climates or at high altitudes.

Prevent Hydrolock: By ensuring that the engine’s air supply remains above the waterline during water crossings, a snorkel helps prevent hydrolock, a condition where water enters the engine’s cylinders, potentially causing severe damage.

Does a snorkel make your car louder?

On some vehicles, as the snorkel sits on the driver’s side of the vehicle you may hear a more audible intake or ‘sucking’ noise, but realistically, the only disadvantage is that when you update your vehicle, you can’t take your snorkel with you… without leaving a large hole in the fender.

A snorkel itself typically does not make your car louder. The primary purpose of a snorkel is to modify the vehicle’s air intake system to allow it to draw in air from an elevated point, typically above the roof level. This modification is primarily related to enhancing the vehicle’s capability in off-road and challenging environments, such as water crossings and dusty terrains, as well as improving engine performance.

The snorkel’s design focuses on maintaining the engine’s air supply quality and preventing water or debris from entering the intake, rather than altering the vehicle’s noise levels. It doesn’t directly impact the exhaust system or the sound produced by the engine.

However, it’s important to note that some individuals may perceive a slight increase in engine noise when using a snorkel, but this is usually due to changes in airflow patterns and resonance within the air intake system. Any such noise difference is typically minimal and not a primary consideration when installing a snorkel.

If you experience a significant increase in engine noise after installing a snorkel, it may be related to other factors, such as changes in airflow or vibrations. In such cases, consulting with a professional mechanic or an expert in snorkel installations can help address and resolve any noise concerns.
