2003 Toyota LandCruiser spark plugs – what’s fitted and what to service

For the 2003 Toyota LandCruiser, spark plugs are relevant if the vehicle runs the 4.7‑litre petrol V8 (engine code 2UZ‑FE). Toyota’s 100 Series service and repair literature for UZJ100 (2UZ‑FE) and major plug catalogues from Denso and NGK list iridium spark plugs for this engine (e.g., Denso SK20R11). By contrast, the 1HD‑FTE and 1HZ diesel LandCruiser engines don’t use spark plugs at all
