Is your Toyota diesel showing signs of airflow restriction or increased dust ingress? At Just Autos, we’ve identified that certain factory airbox designs may struggle to provide optimal filtration in extreme Australian conditions. In response, we’ve developed aftermarket airbox solutions tailored for Toyota diesel vehicles—designed to support improved airflow and filtration in demanding environments.
In challenging Australian conditions—particularly during off-road use or heavy towing—some Toyota models such as the VDJ200, 300 Series, and GDJ70 LandCruisers may experience reduced airbox sealing performance. This can allow fine dust particles to enter the intake system, a phenomenon sometimes referred to as “dusting.”
To help address this, Just Autos offers a range of in-house developed airbox upgrades designed for better sealing, filtration support, and added protection in dusty environments.
As one of Australia’s leading diesel performance specialists, Just Autos is trusted by 4WD owners across Queensland and beyond. From our headquarters in Nambour on the Sunshine Coast, we’ve built our reputation on precision engineering, vehicle-specific tuning, and real-world performance insight.
Contact our team today to explore the ideal airbox solution for your Toyota diesel*.
Engine dusting can occur when fine dust bypasses an air filtration system, entering the engine and contacting sensitive components such as turbochargers, cylinder walls, and piston rings. In harsh or off-road conditions, this can accelerate wear over time. Upgraded air filtration can help reduce this risk.
In our experience, vehicles like the VDJ200, 300 Series, and GDJ70 LandCruisers, as well as the Hilux, may benefit from enhanced filtration—particularly in dusty environments. Our airbox upgrades are designed to improve sealing and airflow, helping support long-term engine reliability.
While better airflow may contribute to combustion efficiency, fuel economy outcomes depend on many factors, including driving style and conditions. We do not guarantee fuel efficiency improvements.
