Mitsubishi Pajero iO 2.0L 4G94 Headers – Wildcat WILD248

Wildcat WILD248 exhaust headers (extractors) are designed for the Mitsubishi Pajero iO fitted with the 2.0L 4G94 petrol engine.

Featuring an interference-style extractor design, WILD248 replaces the restrictive factory exhaust manifold with larger, smoother-flowing pipework. The design helps improve exhaust gas flow and scavenging to reduce restriction and improve torque, throttle response and overall engine performance, making these headers suitable for everyday street, touring and 4WD applications.

Why Good Headers & Exhaust Systems Matter

At 4,000 rpm, the 2.0L 4G94 engine draws in approximately 4,000 litres of intake air per minute and expels around 12,000 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

Apply penetrating lubricant such as WD-40 or similar to the manifold studs, nuts and exhaust fasteners before removal. Inspect the existing mounting hardware and exhaust connections before installation. Trial-fit the header and exhaust connection before fully tightening the system, and 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.

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