Module 6: Toyota LandCruiser 300 Series Performance & Protection

A tough, traditional style snorkel built to handle the harshest off road environments. Maintains factory airbox connection and ensures clean, cool air delivery in dusty or wet conditions.

Flow-optimised for performance setups, the ARMAX snorkel provides increased air intake volume and efficiency – ideal for vehicles running exhaust, tune, or other performance upgrades.

This 3.5” stainless steel DPF back system improves exhaust flow without compromising emissions compliance. Expect lower exhaust gas temperatures, reduced backpressure, and a deeper exhaust note – all while retaining factory sensors and compatibility.

The HPD transmission cooler kit is the only 50mm bar & plate transcooler core of its kind in Australia—built tough for extreme conditions.

Designed specifically for the 10-speed auto LC300, this kit delivers a proven 25°C drop in transmission fluid temperatures, reducing strain on your drivetrain and supporting better long-term reliability. Engineered with CNC-machined billet end tanks, stainless steel brackets, and heavy-duty braided lines, this is a complete bolt-on solution that performs when your LandCruiser is under load.

Key Features:

• Reduced & stable ATF temps (25–45°C lower)
• Protects the 10-speed auto under heavy use
• Improves cooling system efficiency
• Extends transmission and ATF service life

Pairs perfectly with our GVM and towing upgrade packages.

Eliminate heat soak and restore full power in your 300 Series LandCruiser with the HPD upgraded heat exchanger.

The factory side-mounted coolers struggle with airflow—especially when towing in hot conditions—leading to high intake temps and noticeable power loss. The HPD front-mount bar & plate heat exchanger is dyno and road tested to reduce coolant temps by up to 20°C, maintaining consistent performance even under heavy load.

This kit integrates perfectly with the HPD Transmission Cooler Kit.

Key Features:

• CNC billet alloy end tanks
• No-drill, no-cut fitment
• Real-world tested: 2.75x improvement in power retention under load

Proven to prevent power loss when towing in harsh Aussie conditions—this is a must-have upgrade for anyone serious about performance and reliability.

Australian made and engineered specifically for the LandCruiser 300, the HPD catch can prevents oil vapour from entering the intake system, reducing carbon buildup on intake valves and improving long term engine health. Includes custom brackets and hose fittings for a clean, factory style install.

Designed to protect your factory fuel system from water and particulates, this kit includes a 30-micron primary filter mounted before the OEM system. A must-have for outback travel where fuel quality is unpredictable – includes a clear bowl and water sensor for easy monitoring.

Water crossings are no issue with this complete breather setup for the front diff, rear diff, gearbox and transfer case. All high quality components, with a central manifold mounted high in the engine bay for maximum protection.
