If you’re an off-road enthusiast who owns a Toyota Hilux, you’re probably familiar with the challenges that come with navigating through water crossings and dusty terrain. Fortunately, there’s a simple solution that can help protect your engine and keep your Hilux running smoothly: installing a snorkel.
In this article, we’ll cover everything you need to know about installing a snorkel on your Hilux, from what a snorkel is and how it works to the benefits of installing one and the steps you need to follow to get it done.
What is a Hilux Snorkel?
A snorkel is a device that allows your engine to breathe air from a higher position than the factory air intake. This means that when you’re driving through water, dust, or mud, your engine will be able to draw in cleaner, cooler air from above, rather than sucking in water or debris from below.
A Hilux snorkel is specifically designed for Toyota Hilux trucks and is made of durable materials like polyethylene, which can withstand extreme weather conditions and off-road abuse.
Benefits of Installing a Hilux Snorkel
Installing a 4wd snorkels on your Hilux comes with several benefits that can improve your off-road driving experience. Here are some of the main advantages:
- Improved Water Crossing Capability: With a snorkel, you can safely cross rivers and streams without worrying about water getting into your engine. The snorkel allows your engine to breathe air from the top of the vehicle, keeping it safe from water damage.
- Cleaner Air Intake: A snorkel draws in air from above the vehicle, which means it is cleaner and free from the dust and debris that can accumulate on the ground. This can help keep your engine running smoothly and prevent damage to your air filter.
- Better Engine Performance: With a snorkel, your engine can breathe in cooler air, which can improve its performance and fuel efficiency. Cooler air is denser than warm air, so it contains more oxygen, which can lead to better combustion and more power.
How to Install a Hilux Snorkel
Now that you know the benefits of installing a snorkel on your Hilux, let’s go through the steps you need to follow to get it done. Here’s a breakdown of the process:
Step 1: Gather Necessary Tools and Materials
Before you start installing your snorkel, make sure you have all the necessary tools and materials on hand. Here’s a list of what you’ll need:
- Hilux snorkel kit
- Drill and drill bits
- Hole saw
- Silicone sealant
- Socket wrench set
- Screwdrivers
- Pliers
- Electrical tape
- Marker pen
Step 2: Remove Factory Air Intake
The first step in installing your Hilux snorkel is to remove the factory air intake. This is typically located on the passenger side of the vehicle, near the front wheel well.
To remove it, you’ll need to loosen the clamps that hold it in place using your socket wrench set. Then, disconnect any electrical connections and remove the intake from the vehicle.
Step 3: Install Snorkel Body
Once you’ve removed the factory air intake, it’s time to install the snorkel body. This is the main part of the snorkel that attaches to the vehicle’s A-pillar.
To install it, you’ll need to follow the instructions that come with your snorkel kit. Typically, you’ll need to drill a hole in the A-pillar using a hole saw, and then use the included hardware to attach the snorkel body to the vehicle.
Step 4: Install Snorkel Head
After you’ve installed the snorkel body, it’s time to attach the snorkel head. This is the part of the snorkel that sits on top of the vehicle and draws in air.
To install it, you’ll need to follow the instructions that come with your snorkel kit. Typically, you’ll need to drill a hole in the hood of your vehicle using a hole saw, and then attach the snorkel head to the snorkel body using the included hardware.
Step 5: Seal All Connections
Once you’ve installed the snorkel body and head, it’s important to seal all the connections to ensure that no water or debris can get into your engine.
To do this, you’ll need to apply silicone sealant to all the connections between the snorkel body, head, and A-pillar. You may also want to use electrical tape to secure any loose wiring or connections.
Step 6: Test the Snorkel
After you’ve installed and sealed your snorkel, it’s important to test it to make sure it’s working properly.
To do this, start your vehicle and check for any air leaks or abnormal engine sounds. You can also test your snorkel by driving through shallow water or dusty terrain and monitoring your engine’s performance.

Maintenance and Care of Hilux Snorkels
Once you’ve installed a snorkel on your Hilux, it’s important to properly maintain and care for it to ensure that it continues to function properly.
Here are some tips for maintaining and caring for your Hilux snorkel:
- Clean your snorkel regularly to prevent dust, dirt, and debris from building up inside.
- Check the seals and connections periodically to ensure that they’re secure and in good condition.
- Inspect the snorkel head for damage or wear and tear, and replace it if necessary.
- Check the air filter inside the snorkel body regularly, and clean or replace it as needed.
By following these tips, you can help ensure that your Hilux snorkel lasts for years and continues to provide clean air intake and protection for your engine.
Customizing Your Hilux Snorkel
While snorkels come in a standard design, there are ways to customize them to suit your personal preferences or specific needs.
Here are some customization options for your Hilux snorkel:
- Color: Many snorkels come in black, but you can also find them in other colors to match your vehicle’s paint job or add a pop of color.
- Head design: Some snorkel heads come in different shapes or sizes, which can affect the amount of air flow and the look of your vehicle.
- Air ram: An air ram is an attachment that can be added to the snorkel head to increase air flow and improve engine performance.
- Pre-cleaner: A pre-cleaner is a filter that can be added to the top of the snorkel head to prevent dust and debris from entering the engine. This is particularly useful for off-road driving in dusty conditions.
By customizing your Hilux snorkel, you can not only improve the performance of your vehicle, but also add a personal touch to its appearance.
