Vehicle snorkels are air intake mechanisms that allow vehicles with air-breathing internal combustion engines to cross rivers or flooded areas without water entering the engine and causing damage. They are commonly used by military vehicles and off-road driving enthusiasts. Australia has many deep water crossings and flooded areas, which makes snorkels particularly useful for Australian drivers. Snorkels also prevent dust intake, which is beneficial in Australia's dusty environment. Some people also install snorkels on their vehicles for aesthetic reasons or because they are a standard feature on many Australian cars.

What You'll Learn
Snorkels prevent water intake, which can destroy engines
Snorkels are more common in Australia than in other countries, such as the United States and Canada. This is due to the country's frequent deep water crossings and flooding, which require snorkels to prevent water intake and engine destruction.
A snorkel is an extension of the factory air intake that allows a car to suck air from a higher location. This is important because water can easily get flicked or pushed into the air intake, which can lead to water intake and engine damage. A snorkel dramatically decreases the chances of water getting into the engine, as it sucks in air that is higher off the ground and, therefore, cleaner.
Without a snorkel, water will run into places you don't expect, and it only takes a teaspoon of water to completely destroy a motor. This can lead to hydraulic lock, where the engine seizes, stalls, and forward progress ends. Water won't compress like air, so it forces things to bend or break, resulting in serious engine damage.
In addition to preventing water intake, snorkels also improve airflow and prevent dust intake, which is beneficial in dusty environments. They are not very expensive, and they can provide peace of mind when travelling in the Outback, where it is not uncommon to have to ford deep water.

They are useful for river crossings and floods
Snorkels are useful for river crossings and floods in Australia. They are an extension of the factory air intake, allowing vehicles to suck air from a higher location. This reduces the chances of water entering the engine, which can cause serious damage. A teaspoon of water is enough to destroy a motor, leading to expensive replacements.
In addition to preventing water intake, snorkels also improve airflow and provide cleaner air by reducing dust intake. This is particularly beneficial in Australia, where there are many open lands and off-road driving. The country experiences a significant amount of rainfall in a short period, leading to deep water crossings and floods.
Snorkels are commonly seen on off-road vehicles in Australia, and they are available as aftermarket accessories or "universal" kits. They are also standard on many vehicles, such as the Isuzu D-Max utes and MU-X SUVs. When water levels are extremely high, a car bra (tarp) can be placed across the front of the vehicle to reduce potential damage to the radiator.
While some people install snorkels for their functionality, others do it for aesthetic reasons or simply because they can. However, it is important to note that snorkels should be properly sealed to be effective. A poorly sealed snorkel can still allow water to enter the engine, causing damage.

Snorkels provide cleaner air and filters
Snorkels are more common in Australia than in the United States, especially in off-road vehicles. They are used to prevent water intake and to provide cleaner air and filters.
A snorkel is an extension of the factory air intake, allowing vehicles to suck air from a higher location. This reduces the chances of water getting into the engine, as water can easily get flicked or pushed into the air intake, causing damage. A good seal is essential to prevent water from entering the airbox.
Snorkels also provide cleaner air by sucking air that is higher off the ground, away from dust and other contaminants. This is particularly useful in Australia, where there are many river crossings and dusty environments.
In addition to preventing water intake and providing cleaner air, snorkels can also improve airflow and engine cooling. They are available as aftermarket accessories or as part of a "universal" kit, and can be installed by the vehicle owner.
While snorkels are practical, some people may also install them for aesthetic reasons or because they are standard on many vehicles in Australia.

They are popular aftermarket accessories for off-road vehicles
In Australia, snorkels are commonly seen on off-road vehicles, and their popularity may be attributed to several factors. Firstly, Australia has numerous river crossings and regions that are prone to flooding, making snorkels a practical addition for off-road enthusiasts. Secondly, the country experiences a significant amount of dust, and snorkels help prevent dust intake, keeping the engine and air filters cleaner. Additionally, the unique geography of Australia, with its vast open lands and remote areas, may contribute to the popularity of snorkels as they provide peace of mind when travelling through deep water or dusty conditions.
The aesthetic appeal of snorkels also plays a role in their popularity. Some people install snorkels on their vehicles just because they can or for the \"looks cool\" factor. However, it is important to note that while snorkels offer benefits, they are not always necessary for casual off-road use. Some vehicle owners may opt for them as a fashion statement or due to their association with rugged, off-road capabilities.
Furthermore, snorkels can provide additional benefits to diesel engines, which are common in Australia. They promote better airflow by drawing in cooler air, enhancing engine performance. The availability of popular Australian-made snorkel brands, such as Safari snorkels, also contributes to their widespread adoption in the country.
Overall, snorkels are popular aftermarket accessories for off-road vehicles in Australia due to their practical advantages in water crossings and dusty conditions, as well as their aesthetic appeal and perceived benefits to engine performance.

Snorkels are also used for dust intake prevention
Snorkels are a common sight on many Australian cars, and while some people speculate that they are just for show or for their aesthetic benefits, they do serve an important purpose. Snorkels are not only useful for preventing water intake but also for dust intake prevention.
Australia is known for its vast and rugged Outback landscapes, and when driving in these areas, it is not uncommon to encounter deep water crossings and dusty conditions. A snorkel allows the engine to suck in air from a higher location, reducing the chances of dust and other contaminants from being drawn into the engine. This is especially important in dusty environments, as dust can cause significant damage to the engine if it is not properly filtered.
The snorkel is typically routed through the front fender or the hood, extending upwards to the roofline. This design enables the snorkel to draw in air that is higher off the ground and less likely to be contaminated with dust and other particles. By sucking in cleaner air, the snorkel helps to improve airflow and enhance the overall performance of the engine.
Additionally, the use of snorkels can provide peace of mind when travelling in remote areas. Even a small amount of water entering the engine can cause serious damage, including hydraulic lock and engine seizure. By installing a snorkel, drivers can have added assurance that their vehicles are better protected from water and dust intake, reducing the likelihood of costly repairs.
While snorkels are not necessary for all vehicles, particularly those that primarily operate in urban areas, they can be a valuable investment for those who frequently venture off-road or in dusty environments. Snorkels offer a practical solution to the challenges posed by Australia's diverse and often extreme terrain, ensuring a safer and more enjoyable driving experience.
