When converting a GU Patrol to an LS platform or 6BT engine, airflow and reliability become critical. Factory airboxes are rarely designed to handle the increased demands of engine conversions, particularly when paired with turbo upgrades or custom intake systems.
The GU LS1 panel filter airbox from Radius Fabrications has been purpose built to solve this problem. Designed specifically for LS converted GU Patrols, this high performance airbox delivers improved airflow, robust construction and a clean factory style finish suited to serious builds.

Built Specifically for LS and 6BT Conversions
Engine conversions are not one size fits all. LS1, LS2, LS3 and 6BT setups require greater intake capacity and more durable components than standard factory configurations. This GU airbox is engineered to suit these popular conversion platforms, providing a dedicated solution rather than a modified factory part.
With fixed 4 inch inlet and outlet ports, the airbox is optimised for high flow performance. These larger ports are designed to support increased air demand from upgraded motors, helping to maintain consistent airflow under load and during off road conditions.
The airbox is supplied with a Ryco high flow panel filter, ensuring reliable filtration while maintaining performance. This combination provides the balance between protection and airflow that LS converted Patrol owners expect.
Premium TIG Welded Construction
Durability matters, especially in Australian conditions. Off road driving, touring and towing all expose engine bays to heat, dust and vibration.
The Radius Fabrications GU LS1 panel filter airbox is fully constructed using TIG welded aluminium, offering strength without unnecessary weight. The precision welds and clean finish give the airbox a professional appearance, making it suitable for both performance builds and tidy touring setups.
Every unit is manufactured in Australia, ensuring consistent quality and attention to detail. Radius Fabrications has built a reputation for producing high performance intake components that are designed to last, not just look the part.

Designed for Clean, Factory Style Fitment
One of the key advantages of this GU LS converted airbox is its ability to retain a clean, factory style appearance. Engine conversions often result in cluttered engine bays, particularly when universal or improvised intake components are used.
This airbox includes mounting brackets designed to suit GU Patrol conversions, helping to achieve a secure and professional installation. While piping from the airbox to the turbo is not included, this allows flexibility for custom configurations depending on your specific engine and turbo setup.
That flexibility is essential for LS and 6BT builds, where turbo positioning and intercooler routing can vary significantly. By supplying the airbox and filter only, Radius Fabrications allows builders to tailor the remainder of the intake system to their exact requirements.
Compatibility and Fitment Considerations
This GU LS1 panel filter airbox is designed to suit:
LS1 conversions
LS2 conversions
LS3 conversions
6BT conversions
It can align with a Safari snorkel, although minor trimming or adjustment may be required depending on your engine conversion and piping layout. As with any custom build, final fitment may vary slightly based on individual vehicle configuration.
For vehicles running a dual battery setup, modification may be required. In some cases, relocating the secondary battery or opting for a pod style airbox may provide better clearance. Radius Fabrications also offers alternative intake solutions to suit different layouts.

Performance Benefits for LS Converted GU Patrols
Upgrading to a dedicated LS conversion airbox provides several advantages over modified factory units.
Improved airflow capacity to support higher output engines
Reliable filtration with a Ryco high flow panel filter
Stronger construction suited to harsh off road conditions
Cleaner engine bay presentation
Purpose built design rather than adapted components
For GU Patrol owners investing in an LS1, LS2, LS3 or 6BT conversion, the intake system should match the performance potential of the engine. Restrictive or poorly sealed airboxes can compromise both power delivery and engine protection.
By choosing a purpose built solution from Radius Fabrications, owners can ensure their intake system is engineered to support their conversion properly.
Australian Made Quality
Radius Fabrications designs and manufactures its products in Australia, building components that are suited to local conditions. From touring in remote regions to heavy towing and off road use, Australian four wheel drive enthusiasts demand reliability.
The GU LS1 panel filter airbox reflects that approach. It is not a generic aftermarket part. It is built specifically for LS converted GU Patrols and engineered with performance and longevity in mind.
Whether you are completing a fresh engine conversion or upgrading an existing setup, this airbox provides a durable and performance focused intake solution.
