LS converted Nissan Patrols are built for serious touring and performance, often operating in some of the toughest conditions Australia has to offer. Increased power output and engine bay heat place higher demands on the air intake system, making proper airflow and filtration critical. We design and manufacture airboxes that support these demands while protecting the engine from dust and water ingress.
Our custom airbox to suit Nissan Patrol GU LS1 panel filter guard mounted configurations is purpose built for LS converted vehicles. This design reflects our long standing experience fabricating airboxes for Patrol platforms and our focus on performance driven engineering.

Built on Over a Decade of Patrol Airbox Experience
We have been fabricating airboxes for Nissan Patrols for more than a decade. Our work with GU and GQ models is where Radius Fabrications began, and these vehicles continue to influence our approach to intake design.
Years of hands on fabrication and real world testing have allowed us to refine our designs for Australian touring conditions. Dust, heat, vibration, and water exposure are all considered during the development of every Patrol airbox we produce.
Designed Specifically for LS Converted Patrols
LS engine conversions require a different intake solution compared to factory configurations. Increased airflow requirements and engine bay layout changes mean a standard airbox is often no longer suitable.
This guard mounted LS1 panel filter airbox has been engineered specifically for LS converted GU Patrols. The design supports improved cold air intake while maintaining a sealed system that helps protect against dust and water ingestion during off road use.
Fully TIG Welded Aluminium Construction
Every Nissan Patrol GU LS1 airbox is manufactured using fully TIG welded aluminium construction. This fabrication method delivers strength, heat resistance, and long term durability in harsh operating environments.
Aluminium construction is well suited to vehicles that experience constant vibration and temperature fluctuations. The rigid structure helps maintain sealing integrity over time, supporting consistent airflow and reliable engine protection.
Four Inch Inlet and Outlet Ports for Maximum Airflow
This airbox features four inch inlet and outlet ports designed to support the airflow demands of LS powered Patrols. Maintaining unrestricted airflow is essential for engine efficiency, throttle response, and overall drivability.
The internal design focuses on smooth airflow delivery while maintaining effective filtration. This balance is particularly important for touring vehicles that operate under load for extended periods.
High Flow Aeroflow Filtration
Each airbox kit is supplied with an Aeroflow high flow filter that supports increased airflow while maintaining filtration efficiency. Clean air delivery plays a major role in protecting internal engine components from premature wear.
When paired with a sealed aluminium airbox, the filter helps maintain consistent intake performance across dusty tracks, highways, and remote touring routes.
Engine Protection in Dusty and Wet Conditions
Australian touring often involves fine dust, creek crossings, and unpredictable weather. This airbox has been engineered to reduce the risk of dust and water ingestion, supporting engine reliability in challenging environments.
Whether navigating remote tracks or idling through water crossings, a properly designed airbox provides an added layer of protection for LS converted Patrols.
Compatible with Common Snorkel Systems
This Nissan Patrol GU LS1 airbox is compatible with Radius Fabrications snorkels and Safari snorkel systems. Pairing the airbox with a quality snorkel supports improved cold air intake and water crossing capability.
A well matched intake setup helps maintain airflow consistency and reliable performance in a wide range of driving conditions. More information is available at https://radiusfabrications.com.au/products/gu-airbox-4
What Is Included in the Airbox Kit
Each kit includes a Radius Fabrications Patrol Series airbox with four inch inlet and outlet ports, an Aeroflow high flow filter, a mounting bracket kit, a Radius Fabrications branding plate, and an installation instruction sheet.
This kit does not include piping from the airbox to the turbo, allowing flexibility to suit different LS conversion setups.
Australian Made Quality You Can Trust
All our airboxes are designed and manufactured in Australia. Local fabrication allows us to maintain strict quality control and build products that reflect real world Australian driving conditions.
We apply proven fabrication techniques, precision design, and practical experience to every airbox we produce, ensuring long term durability and performance.
A Purpose Built Intake Solution for LS Patrols
Choosing the right airbox is essential for protecting your engine and supporting performance in demanding environments. Our Nissan Patrol GU LS1 panel filter guard mounted airbox is designed for drivers who value durability, airflow efficiency, and reliable protection.
