2016 Toyota Land Cruiser spark plugs: what they do and when to replace them

Checking against Toyota’s technical literature shows spark plugs are relevant on petrol 2016 Land Cruiser models, but not on diesel versions. The 2016 Land Cruiser’s petrol V8s (such as the UR-family/3UR-FE in some markets) use iridium spark plugs, noted in the 2016 Toyota Land Cruiser Owner’s Manual maintenance schedule and Toyota workshop manuals. The 4.5‑litre V8 diesel (1VD‑FTV) uses compression ignition with glow plugs, so it has no spark plugs at all—this is standard diesel design explained in Toyota’s 1VD‑FTV engine manuals.

For owners of petrol 2016 Land Cruisers, spark plugs are a small but mighty part of how the big V8 runs. Each plug ignites the air–fuel mix in its cylinder, so clean, correctly gapped iridium plugs help the Cruiser start crisply, idle smoothly and pull hard when towing or touring. Toyota specifies long‑life iridium plugs for these engines
