Pacemaker PH12680 headers (extractors) are designed for selected Toyota LandCruiser 100 Series UZJ100 models fitted with the 4.7L V8 2UZ-FE petrol engine.
These interference-design headers replace the restrictive factory exhaust manifolds with mandrel-bent pipework designed to improve exhaust flow and scavenging. With 38mm primary pipes, 45mm secondary pipes and 57mm outlets, PH12680 headers are designed to improve torque, throttle response and overall engine performance while retaining excellent drivability for street, touring, towing and 4WD applications.
At 4,000 rpm, the 4.7L 2UZ-FE V8 draws in approximately 9,400 litres of intake air per minute and expels around 28,200 litres of exhaust gas per minute at approximately 600°C.
A well-designed header and exhaust system helps reduce unnecessary exhaust restriction and improve cylinder scavenging, contributing to improved exhaust flow, torque, throttle response and engine performance.
Pacemaker PH12680 headers are backed by Pacemaker's 2-year manufacturer warranty, subject to standard warranty conditions.
For vehicles manufactured from 1986 onwards, modifications to the exhaust system, catalytic converters or other emissions-control equipment must comply with applicable vehicle emissions and registration regulations. It is the vehicle owner's responsibility to ensure the completed installation complies with the requirements applicable in their state or territory.
