2007 Toyota Land Cruiser Spark Plugs

For the 2007 Toyota Land Cruiser, spark plugs are relevant on petrol models but not on diesels. Technical sources such as Toyota workshop manuals for UZJ100/UZJ200, Toyota scheduled maintenance guides, and Denso/NGK application catalogues confirm that the 4.7L petrol V8 (2UZ-FE) runs eight spark plugs with coil-on-plug ignition, while the diesel engines (1HD-FTE in late 100 Series and 1VD-FTV in early 200 Series) use compression ignition with glow plugs instead of spark plugs. The advice below applies to petrol V8 variants.

On the 2UZ-FE petrol V8, spark plugs do the heavy lifting to ignite the air–fuel mix, keeping the big Cruiser running smooth and dependable whether it’s towing, touring, or tackling corrugations. Iridium-tipped plugs (commonly specified for this engine, e.g., Denso SK20R11 or equivalent NGK) offer strong spark energy, durability, and stable idle. Toyota’s maintenance guidance and leading plug makers generally place these plugs on a long-life service interval — typically in the 100,000 to 160,000 kilometre range depending on conditions and plug type. Many AU/NZ schedules land around the 100,000 km mark for inspection/replacement.

As part of routine servicing on a 2007 Land Cruiser petrol V8, it’s smart to check plug condition and the coil boots under the bonnet. Fine-wire iridium tips are pre-gapped by the manufacturer (usually around 1.1 mm) and shouldn’t be forced open or closed, as that can damage the precious-metal tip. If removal is on the cards, work on a cool engine, blow debris out of the plug wells before loosening, and install new plugs by hand first to avoid cross-threading. Torque them to the specification on the plug maker’s data sheet or Toyota’s manual
