If you have performed an engine conversion on your Nissan GU Patrol, you are likely looking for a way to ensure that your new powerplant is operating with the efficiency and power it was designed for. Whether you have swapped in a high revving LS1, LS2, or LS3, or the legendary torque of a 6BT, managing your intake system is a critical step in the build process. At Radius Fabrications, we have developed the GU Airbox Panel Filter specifically for converted vehicles that require increased airflow and long term durability in Australian conditions.

Purpose Built For High Performance Engine Conversions
The standard factory airbox in a GU Patrol was never designed to feed the air requirements of a modern V8 or a large displacement turbo diesel. When you move away from the original engine, the space and flow requirements change significantly. Our GU Airbox is crafted from high quality ally and is fully TIG welded to provide a professional finish that complements any high end conversion. It is designed to offer a clean, factory style appearance while providing the massive boost in performance that converted motors demand. By choosing a purpose built solution, you avoid the pitfalls of restrictive universal filters and ensure your engine bay remains organised and functional.
Optimised Airflow With 4 Inch Ports
To satisfy the breathing requirements of an LS or 6BT engine, our airbox features 4 inch inlet and outlet ports. This size was chosen specifically to minimise intake restriction, allowing your engine to draw in the volume of air needed for optimal combustion. Improved airflow directly translates to better throttle response and overall engine efficiency, which is vital whether you are towing a heavy load or navigating technical off road terrain. By providing a consistent and voluminous air supply, we help you get the most out of your engine conversion investment.

Reliable Filtration With Ryco High Flow Technology
Performance should never come at the expense of protection. Australia is known for its fine dust and harsh environments, which can be devastating to a high performance engine if the filtration is inadequate. Every Radius Fabrications GU Airbox is supplied with a Ryco high flow panel filter. This filter is designed to provide excellent protection against contaminants while still allowing for the high flow rates required by converted engines. The panel filter design offers a large surface area, ensuring that your engine stays protected over long distances and through the dustiest of tracks without significantly impacting airflow.
Australian Made Quality From Capalaba
We take immense pride in our local manufacturing process. Every airbox we sell is designed and fabricated in Australia at our workshop in Capalaba, Queensland. This allows us to maintain complete control over the quality of our products, ensuring that every TIG weld is perfect and every bracket is built to last. When you purchase from us, you are supporting local tradesmen and receiving a product that has been tested in the very environments you plan to explore. Our airboxes are available in a variety of finishes, including polished stainless or a durable powder coated black, allowing you to customise the look of your engine bay.

Compatibility With Popular Conversion Setups
Our GU Airbox is one of the most versatile options on the market for converted Patrols. It has been designed specifically to suit the following engine conversions:
-
LS1 V8 Conversions
-
LS2 V8 Conversions
-
LS3 V8 Conversions
-
6BT Turbo Diesel Conversions
By targeting these specific engines, we have ensured that the airbox provides the right balance of fitment and performance. It is important to note that while this airbox is highly versatile, it is not suitable for vehicles with a dual battery setup in the standard location. If you are running a secondary battery, it will need to be relocated to provide the necessary clearance for this high flow unit. Alternatively, we recommend looking at our pod style airboxes for more compact fitment options.
Custom Flexibility For Your Unique Build
No two engine conversions are exactly the same, which is why we provide a kit that offers flexibility. Our kit includes the airbox with its 4 inch ports, the Ryco filter, mounting brackets, and a Radius Fab branding plate. However, we do not include the piping from the airbox to the turbo or throttle body. We do this intentionally to allow you to custom fabricate the plumbing to suit your specific engine placement, turbo choice, and manifold configuration. This ensures that you get a truly bespoke fit that works perfectly with your unique setup rather than a compromise that might not clear other components in your engine bay.

Installation And Fitment Considerations
We want your installation process to be as smooth as possible. Our kit comes with an instruction sheet to guide you through the process, and the included mounting brackets are designed for a secure fit. Please be aware that depending on the specific engine conversion and the type of snorkel you are using, minor adjustments or trimming may be required. For example, while our airbox can be aligned with a Safari snorkel, the specific piping and engine placement may necessitate some minor modifications for the perfect fit. We recommend planning your layout carefully, especially if you are integrating other aftermarket accessories.
