Parts for your 2022 Toyota Land cruiser-Spark plugs

2022 Toyota Land Cruiser (LC300) and spark plugs

For Australia and New Zealand, the 2022 Toyota Land Cruiser 300 Series (LC300) is delivered with the 3.3‑litre twin‑turbo V6 diesel (engine code F33A‑FTV). Diesel engines ignite fuel by compression rather than a spark, so this Land Cruiser does not use spark plugs. This aligns with Toyota Australia LC300 specifications and the owner’s manual guidance for the diesel powertrain, and with Toyota technical releases describing the F33A‑FTV’s compression‑ignition design. Overseas, a 3.5‑litre twin‑turbo V6 petrol (V35A‑FTS) is offered in some markets and that engine does use spark plugs, but it wasn’t the fitment for AU/NZ models at launch.

Why no spark plugs on the LC300 diesel? In a diesel, air is squeezed to a very high compression ratio, heating it enough that when fuel is injected, it self‑ignites. Instead of spark plugs, a diesel relies on precise injection timing and, for cold starts, glow plugs that gently pre‑heat the combustion chambers. Once running, the engine’s heat and compression do the rest—no spark required.

For owners, this means there’s no “spark plug service” on a 2022 Land Cruiser diesel. The smarter play is keeping on top of diesel‑specific maintenance: clean fuel delivery, healthy glow plugs, and proper exhaust after‑treatment. Workshops familiar with LC300 servicing will check for cold‑start smoothness (a clue to glow plug performance), ensure the common‑rail system meets pressure targets, and verify DPF health and regeneration history.

If someone has an imported petrol 3.5‑litre twin‑turbo V6 Land Cruiser, that engine uses six iridium spark plugs and will have a plug replacement interval noted in its market‑specific logbook (typically around the 100,000–120,000 km mark for modern Toyota iridium plugs, but always follow the exact manual for that vehicle).

• There are no spark plugs on AU/NZ LC300 diesels—don’t expect a plug change at service time.
• Ask the workshop to check glow plug operation if cold starts are rough or smoky.
• Stick to quality diesel, replace fuel filters on schedule, and keep DPF and EGR systems in good nick for reliable running.

Technical basis: Toyota Australia LC300 model specifications and owner’s manual for the F33A‑FTV diesel confirm compression ignition with glow plugs, while Toyota’s technical information on the V35A‑FTS petrol engine notes conventional spark‑ignition with iridium plugs—explaining the different servicing needs between markets.

Popular questions about 2022toyotalandcruiser sparkplugs

Q1: Does the 2022 Toyota Land Cruiser LC300 in Australia or New Zealand have spark plugs?

No. The AU/NZ LC300 uses the F33A‑FTV 3.3‑litre twin‑turbo diesel, which is a compression‑ignition engine and doesn’t use spark plugs. It relies on high compression, precise fuel injection, and glow plugs for cold starts.

Only some overseas petrol variants (V35A‑FTS) use spark plugs. If the vehicle is an Australian or New Zealand‑delivered LC300, there’s no spark plug service item.

Q2: What replaces spark plug servicing on the LC300 diesel?

Think glow plugs, fuel filtration, and emissions hardware. A good workshop will confirm glow plug performance, replace fuel filters per the logbook, check injector health, and verify the DPF is regenerating properly.

If cold starts are lumpy or there’s excess white smoke, ask for a glow plug and intake/EGR check rather than a spark plug change.

Q3: I’ve got an imported petrol 3.5‑litre twin‑turbo LC300—do I need to change spark plugs?

Yes. The V35A‑FTS petrol uses spark plugs (usually iridium). Intervals vary by market and manual, commonly around 100,000–120,000 kilometres or a set number of months. Always follow the plug spec and gap stated in that vehicle’s owner’s manual.

Use quality, OEM‑equivalent plugs and replace on time to keep fuel economy, power, and smooth starts on point.
