2ZR-FXE iridium plugs last 80,000 km. Worn plugs reduce Atkinson-cycle combustion efficiency and raise fuel consumption.
Prius uses iridium spark plugs — 80,000 km replacement interval. The Atkinson-cycle engine has a different combustion pattern than a conventional engine, which is why standard copper or platinum plugs are not suitable.
