Safari ARMAX is about more than raw power. Each piece lifts torque, trims fuel burns and stretches service life, so your Cruiser keeps pulling strong mile after mile.
Part Number: SS78HFZ
The ARMAX Snorkel feeds the 1HZ engine mountains of cool, clean air through tall, curved inlets positioned high above mud and dust, letting you cross water and grit without choking the motor.
Key Features:
- Australian design, moulded and assembled locally
- Raises the air intake to cut down dust and water ingress
- UV-stable cross-linked polyethylene for lasting toughness
- Water-separating air ram strains out rain and moisture

Why choose the SS78HFZ Safari Snorkel?
When the 1HZ engine is called on, it demands plenty of air. The SS78HFZ gives your rig that airflow while shielding it from heavy mud, salt spray, and tropical downpours. Built from rugged materials with a high mounting point, the snorkel guards your engine and helps it breathe easy, no matter where you roam.

Give your 70 Series LandCruiser the strong, smooth note it deserves while freeing up extra horsepower. The Safari ARMAX 3 mandrel-bent exhaust is engineered to pair with the 1HZ block and Safari Turbo, producing faster gas escape, cooler chamber temps, and longer turbo life.
Exhaust Highlights:

- Mandrel-formed bends for consistent diameter
- Aluminized steel construction to resist corrosion
- Precision 4-bolt flange design ensures a leak-free fit

Benefits:
- Roughly 20 percent lower RPM on the open road.
- Reduced strain means a longer-lasting engine.
- Tuned specifically for turbocharged 1HZ motors.
