The Holden Colorado RG has proven itself as a tough, reliable ute capable of handling serious off-road driving, heavy-duty towing, and daily trade work. But if you're relying on the factory airbox, you may not be giving your engine the airflow, and protection, it truly needs. That's why serious drivers across Australia are turning to Radius Fabrications for a smarter solution.
The Holden Colorado Airbox – RG Model from Radius Fabrications is a high-performance, Australian-made upgrade that significantly improves your engine’s access to clean air while making filter maintenance easier and more reliable. Built from quality aluminium with a durable polycarbonate lid, this airbox isn’t just about performance, it’s about confidence in any terrain.
Why Your RG Colorado Needs an Upgraded Airbox
Whether you’re towing a trailer up the coast or exploring remote bush tracks, the last thing you want is engine performance issues due to dust, water, or debris. The factory airbox in many 4WDs, including the Holden Colorado RG, often falls short in sealing efficiency and airflow optimisation.
Over time, even tiny amounts of dust or moisture can damage internal engine components and reduce power output. That’s where the Radius Fabrications Holden Colorado Airbox makes a serious difference. Designed to be a direct-fit replacement and engineered to withstand Australia's toughest environments, this airbox is the upgrade your Colorado needs to keep performing at its best.
Key Features That Make the Radius Colorado Airbox Stand Out
1. Australian Made and Tested
Unlike generic overseas parts, Radius Fabrications manufactures its airboxes locally, using high-grade materials suited for Australian roads and off-road tracks. This isn’t just about supporting local, it's about ensuring the gear on your ute is built to handle heat, dust, rain, and corrugation.
2. 3D Scanned and CAD Designed for Precision
Every airbox is digitally scanned and computer-modelled for a perfect fit. This ensures seamless installation and maximum compatibility with the Holden Colorado RG engine bay. You won't need to hack, cut, or adapt the product, it bolts into the factory airbox location.
3. Aluminium Body with Clear Polycarbonate Lid
The aluminium body provides structural integrity and resists corrosion, while the tough polycarbonate lid adds practicality. You can easily inspect your filter and airbox internals through the transparent lid without needing to disassemble anything. It’s a smart feature that helps prevent performance loss or costly engine repairs due to unseen filter issues.
4. Designed to Withstand the Elements
Whether you're crossing rivers or charging through red dirt country, the Radius airbox is built for durability. It seals tightly when installed correctly, keeping your filter and engine internals clean and dry in the harshest conditions.
5. Simple Bolt-In Installation
The Holden Colorado Airbox – RG Model is engineered to mount in the factory airbox location. While bracket alignment may vary slightly depending on the model and year, the installation remains straightforward with minimal adjustments.
How a Better Airbox Supports Engine Performance
Good airflow is critical to combustion efficiency. When your engine can breathe more easily, it burns fuel more efficiently, translating to improved throttle response, smoother power delivery, and even better fuel economy.
But just as importantly, clean airflow matters. A factory airbox that allows dust or water to bypass the filter can severely reduce engine life. The Radius airbox upgrade ensures clean, dry air reaches the combustion chamber, supporting both short-term performance and long-term durability.
Easier Maintenance, Less Guesswork
One of the standout features of this airbox is the clear polycarbonate lid. Instead of removing the housing and checking the filter blindly, you can simply look through the lid to identify:
-
Dust or debris buildup
-
Moisture or water ingress
-
Filter clogging or deformation
This means issues can be caught early, long before your performance suffers or engine damage occurs. It’s a simple, effective way to stay in control of your vehicle’s health.
