Toyota LandCruiser FJ60 4.2L 2F Headers 1980–1987 – Wildcat WILD135

Wildcat WILD135 exhaust headers (extractors) are designed for selected Toyota LandCruiser FJ60 models from 1980–1987 fitted with the 4.2L 2F inline 6-cylinder petrol engine.

Featuring an interference 4-2-1 header design, WILD135 uses 38mm primary pipes, 51mm secondary pipes and a 57mm outlet. The tuned pipe configuration is designed to improve exhaust scavenging and reduce exhaust restriction, helping improve torque, throttle response and usable engine performance from the 2F engine.

WILD135 is suitable for applicable manual and automatic transmission vehicles and is designed as a direct-fit replacement for the factory exhaust manifold.

Why Good Headers & Exhaust Systems Matter

At 4,000 rpm, the 4.2L Toyota 2F inline 6-cylinder engine theoretically draws in approximately 8,400 litres of intake air per minute and can expel around 25,200 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

• Apply penetrating lubricant such as WD-40 or similar to the manifold studs, nuts and exhaust fasteners before removal
• Remove all traces of the old manifold gasket before installing the header
• Inspect the cylinder-head sealing surface, studs and threads before installation
• Fit a new DSF032 exhaust manifold/header gasket
• Trial-fit the header before fully tightening the mounting hardware
• Check clearance around the engine mounts, steering, transmission, chassis and surrounding components
• Protect the painted surfaces during trial fitting and installation
• Inspect and re-tighten the mounting hardware after the initial heat cycles

Warranty & Compliance

Wildcat headers are covered by the applicable 2-year manufacturer's warranty subject to standard warranty terms and conditions.

Correct installation and adequate clearance around surrounding components are essential. Vehicle, engine, transmission and exhaust modifications may affect fitment.
