When it comes to getting the most out of your 2005–2015 Toyota Hilux, airflow matters. Whether you’re heading off-road, towing heavy loads, or simply want to future-proof your vehicle, your factory airbox may be holding you back. The good news? There’s a better option, and it's 100% Australian made. Introducing the N70 Hilux Airbox by Radius Fabrications.
This blog covers why replacing your OEM airbox with a high-performance upgrade is essential, how the N70 Hilux Airbox outperforms alternatives, and why so many Hilux drivers across Australia are making the switch.
The Importance of a Quality Airbox for Your N70 Hilux
Your airbox is one of the most vital components in your vehicle’s air intake system. It protects your engine from dust, water, and debris, while providing the clean air needed for combustion. In factory setups, especially on older Hilux models, the airbox may not always provide the best seal or airflow efficiency.
For those who take their 4x4 into harsh Australian conditions, the need for a better-sealed, performance-focused airbox becomes even more critical. That’s where Radius Fabrications' N70 Hilux Airbox comes into play.
Why Choose Radius Fabrications?
Radius Fabrications is an Australian company that understands what local drivers need. Their entire range of 4x4 products, including the N70 Hilux Airbox, is built with rugged Australian conditions in mind. Unlike cheaper overseas options, these parts are made to perform and endure.
The N70 Hilux Airbox is not just an upgrade; it’s a complete rethinking of what an airbox should be.

Engine Protection That Goes Beyond Expectations
Dust and water ingress are leading causes of engine damage in remote and regional Australia. A poorly sealed or worn-out factory airbox can allow contaminants into your engine, leading to wear, inefficiency, and expensive repairs. The N70 Hilux Airbox eliminates this risk by forming a watertight barrier, ensuring your engine breathes nothing but clean air.
Ideal for Snorkel Integration
If you’ve already fitted a snorkel to your Hilux, this airbox is a natural next step. The N70 Hilux Airbox integrates seamlessly with aftermarket snorkels, creating a fully enclosed intake pathway that improves dust and water protection tenfold.
Performance Gains You Can Feel
While the primary purpose of this airbox is protection and reliability, many users also report modest improvements in throttle response and power. That’s due to more efficient airflow and the removal of factory airflow restrictions. When your engine breathes better, it performs better, especially under load or in off-road situations.
A Long-Term Investment in Vehicle Reliability
Unlike some upgrades that are purely cosmetic or marginal, the N70 Hilux Airbox provides long-term value by extending the life of your engine and reducing the risk of costly damage. It’s also a strong selling point should you ever decide to move on from your Hilux.
