Parts for your 2020 Toyota Land cruiser-Spark plugs

2020 Toyota LandCruiser spark plugs: are they used on the 200 Series?

For Australian and New Zealand–market 2020 Toyota LandCruiser 200 Series models, spark plugs are not relevant because these vehicles are fitted with the 4.5‑litre 1VD‑FTV twin‑turbo diesel V8. Diesel engines don’t use spark plugs, they rely on compression ignition to fire the fuel–air mix. This is confirmed by Toyota Australia’s 200 Series specifications for MY2020, which list the 1VD‑FTV diesel only, and by Toyota’s workshop literature for the 1VD‑FTV that details a glow plug system rather than spark ignition.

Instead of spark plugs, the 1VD‑FTV uses glow plugs to pre‑heat the combustion chambers for cold starts. The engine ECU controls the glow system and post‑glow timing to stabilise idle and reduce smoke on cold mornings—standard diesel practice referenced across Toyota’s diesel service manuals and general diesel-engine texts. So if someone’s been told their 2020 LandCruiser needs “new spark plugs”, that advice doesn’t apply to the AU/NZ 200 Series diesel.

Why the confusion? In some markets (for example, North America), the 2020 Land Cruiser is powered by the 5.7‑litre 3UR‑FE petrol V8, which does use spark plugs. Toyota owner’s and service information for that petrol engine specifies iridium spark plugs and scheduled replacement. Different engine, different ignition system.

For local 200 Series owners, the service focus should be on diesel‑specific items rather than spark plugs:

• Healthy glow plugs and glow control—worth checking if there are hard starts, white smoke on cold start, or rough idle when cold.
• Clean fuel system—stick to the fuel filter replacement interval and use quality diesel to protect injectors.
• Strong batteries—diesels need plenty of cranking speed for compression ignition, weak batteries can mimic glow‑plug faults.
• Air intake and EGR cleanliness—helps cold starting and overall drivability.

Technical sources referenced: Toyota Australia 200 Series LandCruiser 2020 specifications (1VD‑FTV twin‑turbo diesel fitment), Toyota 1VD‑FTV diesel engine repair manual (glow plug and compression‑ignition system), and Toyota market literature noting that only the 3UR‑FE petrol variant (sold in other regions) uses spark plugs.

FAQs

Does a 2020 Toyota LandCruiser 200 have spark plugs?
No. The AU/NZ 200 Series runs the 1VD‑FTV twin‑turbo diesel V8, which uses compression ignition and glow plugs, not spark plugs, as documented in Toyota’s diesel engine and vehicle specifications.

What should be serviced instead of spark plugs on a diesel LandCruiser?
Focus on the glow plugs (if cold‑start symptoms appear), fuel filter at the prescribed intervals, battery condition, and air/EGR cleanliness. These have a bigger impact on starting, smooth running, and longevity in the 1VD‑FTV diesel.

Why do some guides say the 2020 LandCruiser needs spark plugs?
They’re referring to the petrol‑engine version sold in other markets (3UR‑FE 5.7‑litre V8), which does use spark plugs. That advice doesn’t apply to the AU/NZ diesel 200 Series.
