The Radius Fabrications 79 Series Airbox is engineered for maximum protection, maximum airflow, and long-term reliability in the harshest touring and off-road environments.
After the success of our 200 Series panel-filter airbox, we built the 79 Series version using the same proven principles. Each unit is CNC designed, laser-cut, TIG welded, and then precision-machined on our 5-axis mill to achieve an exceptionally tight seal around the Toyota 200 Series panel filter. Once the lid is tightened down, you know that close to zero dust is entering your V8 protecting engine performance and longevity for thousands of kilometres.
There’s no clear lid, pod filter, or gimmicks here. This airbox is built for one job: keeping dust and water out of your engine while delivering clean, consistent airflow.
Using the Toyota 200 Series factory panel filter (not included) makes replacement easy anywhere you travel, any dealer or mechanic can supply one.
This is the REAL DEAL panel-filter airbox upgrade for your VDJ LandCruiser.
Airbox Location: Designed to fit the factory position. Brackets may sometimes align to different mounting holes depending on vehicle tolerances.
