Vehicle snorkels are air intake systems that allow vehicles to take in air from a higher location. They are commonly used in Australia due to the country's rugged terrain and frequent deep water crossings. Australian roads often involve traversing rough outback roads and fording deep water, especially in regions like the Blue Mountains and the High Country. The snorkel design raises the air intake, providing peace of mind and protecting engines from water damage. They are particularly useful for diesel engines, which perform better in deep water crossings compared to gas-powered vehicles. Snorkels also prevent dust intake, which is advantageous in Australia's dusty open lands. While some people install snorkels as an aftermarket accessory for off-road driving or aesthetic purposes, others question their necessity for vehicles that primarily operate in urban areas.

What You'll Learn
Snorkels prevent water damage to engines
Snorkels are an effective way to prevent water damage to engines. They are particularly useful for vehicles that need to ford deep water or navigate flooded areas. In such cases, a snorkel can supply air to both the engine and a sealed crew compartment, enabling total submersion.
The snorkel is typically routed through the front fender or the hood, extending to the level of the roofline. This extension allows the vehicle to suck air from a higher location, reducing the risk of water entering the engine bay. Without a snorkel, water can easily contaminate the air intake, leading to serious engine damage. Even a small amount of water, such as a teaspoon, can cause hydraulic lock, resulting in engine seizure and stalling.
In Australia, snorkels are commonly seen on off-road vehicles, especially in the Outback where deep water crossings are frequent. The popularity of snorkels in Australia may also be attributed to their ability to prevent dust intake, which is advantageous in dusty environments.
While snorkels offer protection against water damage, it is important to note that they do not guarantee complete waterproofing. Some snorkels are not fully sealed, and if water reaches a high enough level, it can still leak in and cause damage. Additionally, other components of the vehicle, such as electrical connections and spark plugs, may still be vulnerable to water ingress even with a snorkel installed.
Overall, snorkels provide a level of defence against water damage to engines, making them valuable for vehicles operating in environments with deep water crossings or the possibility of water contamination.

They are useful for deep water crossings
Snorkels are useful for deep water crossings in Australia. They are an extension of the factory air intake, allowing vehicles to suck air from a higher location. This prevents water from getting into the air intake and causing engine failure.
In Australia, there are many deep water crossings and places that are prone to flooding. While some vehicles may not need them, snorkels provide peace of mind and insurance for unexpected deep water crossings. They are particularly useful for diesel engines, which handle deep water crossings better than their gas-powered counterparts.
Snorkels can be routed through the front fenders or the hood, with the intake terminated at the roofline. This design raises the maximum water depth that a vehicle can handle, as it is dictated by the height of the snorkel intake. A well-sealed snorkel with a movable intake head can also help prevent dust intake, which is common in Australia's dusty outback roads.
Overall, snorkels are a useful addition to vehicles in Australia, providing confidence and protection for deep water crossings and dusty conditions. They are relatively inexpensive and can save vehicle owners from costly engine repairs due to water damage.

Snorkels are used for dust intake prevention
Snorkels are an essential accessory for off-road vehicles in Australia, where deep water crossings are common. They are also useful for preventing dust intake, which is a significant issue in the country's dusty terrain.
A snorkel is an extension of the factory air intake, allowing the engine to suck air from a higher location. This prevents contaminants, including dust, from being pushed into the air intake and causing damage to the engine.
In Australia, snorkels are particularly popular on 4WD vehicles, which are commonly used for off-road driving and camping. The snorkel design allows the pipe to run inside the fender, resulting in a cleaner installation and no change to the vehicle's side-to-side clearance.
While some people install snorkels purely for their functionality, others view them as a fashionable accessory, enhancing the appearance of their vehicles. However, it is important to note that snorkels are not a universal necessity. They are most useful for those who frequently encounter deep water crossings or dusty conditions.
For those considering the addition of a snorkel, it is important to ensure proper installation and sealing. This includes sealing all air intake parts inside the engine bay and providing additional sealing for computers, fuse boxes, and interior electronics, which are generally not waterproofed.

They are an extension of the factory air intake
Snorkels are an extension of the factory air intake, allowing vehicles to breathe air from a higher location. This is particularly useful for off-road driving and river crossings, as it prevents water from entering the engine and causing significant damage.
The snorkel design typically involves routing a pipe through the front fender or hood, up to the roofline, where it terminates with an intake. This raised intake provides peace of mind for drivers navigating Australia's rugged terrain and frequent deep water crossings.
The pipe supplies air to both the engine and a sealed crew compartment in military vehicles, enabling total submersion. While civilian vehicles may not require total submersion, a snorkel can prevent water contamination, which can destroy an engine.
In addition to water protection, snorkels also offer benefits in dusty environments. By raising the air intake, snorkels can prevent dust and other contaminants from entering the engine, resulting in cleaner filters and cooler air intake.
For Australian drivers, snorkels provide a practical solution to the challenges posed by the country's unique environment, ensuring a more reliable and durable driving experience.

Snorkels are popular aftermarket accessories
The snorkel design typically involves routing a pipe through one of the front fenders or the hood, up beside the "A-pillar" to the roofline level. Here, it is terminated with an intake to provide air for the engine. While some snorkels are completely sealed, others are simply fresh air extensions, which may not fully protect against water damage.
The popularity of snorkels in Australia may be attributed to several factors. Firstly, the country experiences a significant number of deep water crossings and flooding, especially in certain regions like the Blue Mountains and the tropics, where heavy rainfall is common. Secondly, the dusty conditions in Australia's open land and Outback make snorkels practical for preventing dust intake. Additionally, the diesel engines commonly found in Australian vehicles are better suited for deep water crossings, making snorkels a viable option for many drivers.
Snorkels are also relatively affordable, and some drivers may opt for them simply for aesthetic reasons or as a precautionary measure, even if they do not frequently encounter deep water. However, it is important to note that snorkels are not a guarantee against water damage, and proper maintenance and precautions are still necessary when driving through water.

Frequently asked questions
Snorkels are not standard on all Australian cars, but they are more common in Australia than in some other countries, such as the United States. This is likely because there are many river crossings in Australia, and snorkels can prevent water from entering the engine. They can also prevent dust intake.
Snorkels are an extension of the factory air intake, allowing cars to suck air from a higher location. They are typically routed through the front fenders or the hood, up to the level of the roofline, where they are terminated with an intake.
It is not recommended to drive through water without a snorkel. Even a teaspoon of water can be enough to destroy an engine, leading to very costly replacements.
