Owners of the Toyota 80 Series LandCruiser know how important dependable airflow is when touring, towing or tackling remote tracks. The 1HZ diesel engine is renowned for reliability, but its performance depends heavily on a clean, unrestricted supply of air. Long drives across red dust plains, rugged high-country routes or coastal environments expose the factory intake system to heavy debris and heat. Upgrading to a purpose-built pod filter airbox is one of the most effective ways to support engine longevity and real-world performance.
The Radius Fabrications 80 Series Pod Filter Airbox is built specifically for the 1HZ diesel and replaces the factory housing with a stronger, more efficient design. More information can be found here.
Australian-Built Engineering For Harsh Conditions
This airbox is fully engineered and fabricated in Australia by experienced tradesmen who understand the demands placed on touring vehicles. Every unit is TIG welded, ensuring strength, durability and consistent airflow pathways. The satin black powder-coated finish provides long-term protection against corrosion, vibration, heat and debris.
Drivers searching for terms like 80 Series airbox upgrade, 1HZ pod filter airbox or Toyota LandCruiser airflow improvement will appreciate how this design addresses the limitations of the factory system. The construction quality reflects years of practical experience in local conditions.
Maximum Airflow With A 4 Inch Outlet
One of the key advantages of this airbox is the unrestricted 4 inch outlet that improves airflow compared to the original factory intake. The design supports stronger breathing for the 1HZ engine, especially during heavy loads or extended climbs. Better airflow also contributes to more efficient combustion and cleaner running over long distances.
For owners planning modifications such as touring builds, heavy towing setups or off-road accessories, ensuring the engine receives clean, cool air is essential. This airbox provides that foundation.
High-Performance Pod Filter And Clear Inspection Lid
The included Aeroflow 4 inch pod filter delivers high-flow filtration while protecting the engine from dust, sand and fine debris. This makes it ideal for long-haul outback routes, beach driving and high-dust environments where clogging and restricted airflow become real concerns.
A standout feature of this setup is the clear polycarbonate lid etched with the Radius Fabrications logo. It allows drivers to visually check the filter and internal chamber without removing the cover. When travelling through dusty regions or completing multi-day trips, quick inspections help ensure the engine continues to breathe clean air.

Direct Factory Replacement For The 80 Series 1HZ
This airbox is designed to bolt directly into the factory position on the Toyota 80 Series LandCruiser fitted with the 1HZ diesel engine. While vehicle variations may mean some brackets align with different mounting points, the installation remains straightforward for most setups.
Owners researching 80 Series direct-fit airbox, 1HZ intake upgrade or LandCruiser factory replacement airbox will find this unit offers both compatibility and improvements in performance.
Compatible With Factory And Radius Snorkel Setups
Some LandCruiser owners run the original snorkel while others upgrade to a high-flow aftermarket system. This pod filter airbox is designed to perform effectively with either option, including Radius snorkels. When combined with an efficient snorkel, the airbox supports cleaner air intake when water crossings, dust storms or narrow tracks become part of the journey.
The combination of a Radius airbox and snorkel is commonly chosen for builds that need maximum reliability and long-term durability.
A Long-Term Upgrade For Touring And Off-Road Builds
The 80 Series LandCruiser remains one of Australia’s most respected touring vehicles. Many models continue to serve families, adventurers and workers in tough environments, often decades after rolling off the production line. The Radius Fabrications 80 Series Pod Filter Airbox helps extend the capability and engine life of these vehicles by improving airflow and filtration consistency.
A well-designed intake system plays a vital role in engine protection. By choosing an Australian-built, TIG welded airbox with a high-performance pod filter, owners are investing in long-term reliability for their 1HZ engine.
