Parts for your 2016 Toyota Land cruiser-Spark plugs

2016 Toyota Land Cruiser spark plugs: what’s fitted and what to service

Referencing Toyota’s own service information, owner’s manuals and parts catalogues for the 200 Series: the 2016 Land Cruiser comes in two main flavours. The petrol V8 (URJ200, 5.7‑litre 3UR‑FE) uses spark plugs. The turbo‑diesel V8 (VDJ200, 4.5‑litre 1VD‑FTV), which is the common pick across Australia and New Zealand, does not use spark plugs at all.

Why no spark plugs on the diesel? A diesel ignites fuel by high compression and heat, not a spark. It may use glow plugs to aid cold starts, but there’s no ignition spark event, so “sparkplugs” aren’t relevant on the VDJ200. If your 2016 Land Cruiser is the petrol V8, read on for how spark plugs fit into its servicing.

On the petrol 3UR‑FE, spark plugs are the tiny workhorses that ignite the air–fuel mix each time a cylinder fires. Healthy plugs keep the Land Cruiser starting crisply under the bonnet, idling smoothly, pulling strongly under load, and sipping fuel as efficiently as a big wagon can. Toyota specifies long‑life iridium plugs for this engine, with a replacement interval typically around 192,000 km (120,000 miles) under normal conditions. Dust, frequent towing, short trips, or lots of low‑speed work can justify earlier checks.

• Use the correct OEM‑spec iridium plugs with the proper heat range and reach. Mixing types can cause misfires or pre‑ignition.
• Replace the full set at once. Ageing plugs rarely fail in isolation, and a matched set keeps the V8 balanced.
• Don’t add anti‑seize to modern, plated plug threads, Toyota service information advises dry installation. Over‑lubed threads can skew torque.
• Tighten to the workshop‑manual torque spec and ensure the crush washer seats. Over‑tightening can damage the alloy heads.
• Before removal, blow away dust around each coil and plug tube so grit doesn’t drop into the cylinder.
• Inspect coil boots for hardening or tracking marks, a quick smear of dielectric grease on clean boots helps prevent future arcing.
• If you’re chasing a rough idle, poor economy, or a flashing MIL, scan for misfire codes (e.g., P0300–P0308) and check plug condition and coils.
• Keep the factory gap, iridium fine‑wire plugs are pre‑set and usually shouldn’t be re‑gapped.

With the right plugs, fitted correctly, the 3UR‑FE runs cleaner, smoother and more efficiently, making long Kiwi or Aussie road trips that bit easier.

Does a 2016 Toyota Land Cruiser have spark plugs?

It depends on the engine. The petrol 5.7‑litre V8 (URJ200, 3UR‑FE) uses spark plugs, eight in total, one per cylinder with coil‑on‑plug ignition. The 4.5‑litre twin‑turbo diesel V8 (VDJ200, 1VD‑FTV) uses compression ignition and glow plugs for cold starts, so no spark plugs are fitted.

If you’re unsure, check the fuel type on the rego or the engine code on the build plate. Petrol = spark plugs, diesel = no spark plugs.

How often should spark plugs be changed on the petrol 2016 Land Cruiser?

Toyota specifies long‑life iridium plugs with a typical change interval around 192,000 km under normal service. Heavy towing, dusty outback travel, or short‑trip city use can justify earlier inspection and replacement if fouling or wear is found.

Always fit quality OEM‑spec iridium plugs, replace all eight together, and follow the torque spec in the workshop manual.

What are the signs the plugs need attention?

Hard starting, a lumpy idle, hesitation under load, higher fuel use, or a flashing check‑engine light are classic clues. Scan tools may show misfire codes like P0300–P0308. Pulling a plug may reveal worn electrodes, heavy deposits, or cracked insulators.

Also inspect the coil boots for carbon tracking and moisture in the plug tubes. Sorting plugs and coils together often restores smooth running.
