Toyota Prado 90 Series 3.4L 5VZ-FE Automatic Headers – Wildcat WILD290A

Wildcat WILD290A exhaust headers (extractors) are designed for the Toyota LandCruiser Prado 90 Series fitted with the 3.4L V6 5VZ-FE petrol engine from 1996 to 2002 and a automatic gearbox.

Featuring an interference-style extractor design, WILD290A replaces the restrictive factory exhaust manifolds with larger, smoother-flowing pipework designed to improve exhaust gas flow and scavenging. Improved exhaust flow can help increase low and mid-range torque, throttle response and overall engine performance, making these headers well suited to street, touring, towing and 4WD applications.

What’s Included

• Wildcat WILD290A header / extractor assemblies

Recommended With

Why Good Headers & Exhaust Systems Matter

At 4,000 rpm, the 3.4L 5VZ-FE V6 draws in approximately 6,756 litres of intake air per minute and expels around 20,300 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. Trial-fit both headers and exhaust connections before cutting, welding or fully tightening the system. Protect the painted surfaces during installation to minimise scratching or damage.

Warranty & Compliance

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

Exhaust and emissions requirements vary between Australian states and territories. Installation must retain the catalytic converters, oxygen sensors and any other emissions-control equipment required for the vehicle and comply with the regulations applicable in your state or territory.
