Parts for your 2020 Toyota Land cruiser-Spark plugs

Are spark plugs used on the 2020 Toyota Land Cruiser in Australia and New Zealand?

Based on Toyota Australia and Toyota New Zealand technical specifications and the 200 Series owner’s manual for MY2020, local Land Cruiser wagons were delivered with the 4.5‑litre V8 twin‑turbo diesel (engine code 1VD‑FTV). Diesel engines use compression ignition, so they don’t require spark plugs. Instead, they rely on very high compression and precisely timed fuel injection to ignite the air–fuel mixture. Cold starts are assisted by glow plugs and a glow control system rather than any spark-based ignition.

That’s why a “2020toyotalandcruiser sparkplugs” search won’t turn up a service item for Australian or New Zealand models—there simply aren’t any spark plugs to replace on the 1VD‑FTV. The factory documentation outlines a glow plug indicator on the dash and describes pre‑heating behaviour at low temperatures, reinforcing that ignition is handled by heat and compression, not a spark.

For owners keeping their 2020 Land Cruiser in top nick, attention shifts to diesel-specific maintenance instead of spark plug changes:

• Fuel system care: Replace the fuel filter at the logbook interval and drain the water separator when alerted. Clean fuel is critical for common‑rail injectors.
• Glow system checks: If cold starts are rough or the glow indicator behaves abnormally, have the glow plugs and the glow control circuit tested.
• Air intake and EGR: Periodic inspection and cleaning help maintain smooth breathing and efficient combustion.
• Battery and cranking health: Diesels need strong cranking speed, keep the battery and starter in good condition.
• Regular servicing: Stick to Toyota’s 10,000 km (or time-based) service schedule for oil, filters and inspections, especially if towing or touring.

Note: Some overseas 2020 Land Cruiser variants run petrol V8 engines that do use long‑life iridium spark plugs. If a privately imported petrol model is in question, check the VIN and engine code (e.g., 3UR‑FE) to confirm the correct spark plug type and interval.

Popular questions about 2020 Toyota Land Cruiser spark plugs

Do 2020 Toyota Land Cruisers in Australia or New Zealand have spark plugs?

No. Local 2020 200 Series models are the 4.5‑litre V8 turbo‑diesel (1VD‑FTV), which doesn’t use spark plugs. It uses compression ignition and glow plugs for cold starting. Only petrol variants sold in some overseas markets use spark plugs.

What should be serviced instead of spark plugs on a 2020 Land Cruiser diesel?

Focus on diesel essentials: fuel filter changes per the logbook, draining the water separator when indicated, checking glow plugs if cold starts worsen, keeping the battery strong, and inspecting intake/EGR cleanliness. Regular 10,000 km services keep the common‑rail system happy.

How often do glow plugs or injectors need attention?

Glow plugs aren’t typically a routine replacement item—test them if starting issues appear or a fault code is logged. Fuel filters are periodic (refer to your Toyota schedule), while injector condition is usually assessed over higher mileages, many owners have them checked around 150,000–200,000 km or sooner if there’s smoke, knock, or poor economy.
