Fitment Notes

1FZ-FE Engine Only: WILD043 is designed for the 4.5L 1FZ-FE DOHC 24-valve petrol engine.

Correct Year Range: Although the Toyota 80 Series was introduced in Australia in 1990, the 4.5L 1FZ-FE was not introduced until late 1992. Earlier petrol 80 Series vehicles used the 4.0L 3F/3F-E engine.

Direct Fit: WILD043 is listed as a direct-fit application. However, because these vehicles are now more than 25 years old, check for previous exhaust modifications, engine conversions or non-standard components before installation.

Confirm the chassis and engine code before ordering, particularly on imported or modified vehicles.

What's Included

• 1 x Wildcat WILD043 header/extractor assembly

Gaskets, bolts and other installation hardware should not be assumed to be included unless specifically confirmed before ordering.

Recommended With

DSF084 – replacement exhaust manifold/header gasket.

Before installation, inspect the existing exhaust system, manifold studs, engine mounts and associated mounting hardware.

Why Good Headers & Exhaust Systems Matter

At 4,000 rpm, the 4.5L 1FZ-FE six-cylinder engine theoretically draws approximately 9,000 litres of intake air per minute at 100% volumetric efficiency and expels around 27,000 litres of hot exhaust gas per minute at approximately 600°C.

A well-designed header and exhaust system helps manage this high gas flow efficiently, reducing restriction and improving exhaust scavenging, torque, throttle response and engine performance.

Installation Tips

Before installation, confirm that the vehicle is an FZJ80 LandCruiser fitted with the 4.5L 1FZ-FE engine.

Lubricate threaded fasteners with WD-40 or a similar penetrating lubricant before removal to assist with easier removal and installation.

Professional installation is recommended. After installation and several heat cycles, inspect the exhaust system for leaks and recheck accessible fasteners where appropriate.

Warranty & Compliance

Any catalytic converter, oxygen sensor and other emissions-control equipment required for the particular vehicle must remain correctly installed and operational.

Installation must comply with applicable Australian state or territory requirements relating to emissions, exhaust noise and vehicle modifications.

FAQ

What Toyota LandCruiser does WILD043 fit?
WILD043 is designed for the Toyota LandCruiser FZJ80 80 Series fitted with the 4.5L 1FZ-FE petrol engine.

What is the correct year range?
For the Australian 4.5L 1FZ-FE FZJ80 application, approximately November 1992 to February 1998 is the appropriate range. The 80 Series itself began in 1990, but the 4.5L 1FZ-FE was introduced later.

Does WILD043 fit a 1990 or 1991 LandCruiser 80 Series?
Not if the vehicle still has its original petrol engine. Early Australian 80 Series petrol models used the 4.0L 3F/3F-E. WILD043 is specifically for the later 4.5L 1FZ-FE application.
