Parts for your 2014 Toyota Land cruiser-Ignition leads

2014 Toyota Land Cruiser ignition leads: are they used?

Short answer: no, traditional ignition leads aren’t used on the 2014 Toyota Land Cruiser. Referencing Toyota’s technical literature, the 200 Series line-up in this year either runs the 1VD-FTV 4.5‑litre V8 diesel (common in Australia and New Zealand) or petrol V8s from the UR family (market dependent). The diesel is a compression-ignition engine with glow plugs, not spark plugs, so there are no high-tension leads. The petrol UR engines use coil-on-plug (COP) ignition, where each spark plug has its own ignition coil mounted directly on top—again, no separate lead set.

This is backed by Toyota’s Service Information (TIS) and the Electronic Parts Catalogue (EPC) for the 200 Series: the diesel sections list the Glow Plug System and related control components, and no spark plug or lead set. The petrol ignition sections list “Ignition Coil with Igniter (for No. X Cylinder)” and spark plugs, but no high-tension cords. In other words, there’s nothing to replace that resembles the old-school dizzy-and-leads setup.

Why the change? COP ignition on the petrol V8 reduces energy loss and interference, sharpens spark control, and improves reliability because there’s no long, high-voltage cable to age, arc, or crack. On the diesel V8, spark isn’t part of the game at all—combustion is triggered by compression, so leads simply don’t exist in the system.

What should owners service instead? For diesel models, think glow plugs and their wiring, battery condition, and the glow control module—especially if cold starts get lazy. For petrol models, focus on the ignition coils and long-life iridium spark plugs: inspect for misfire history, oil in plug tubes, cracked coil boots, and follow the logbook intervals for plug replacement. A scan for misfire counters and a visual inspection during scheduled servicing goes a long way.

• Diesel 1VD-FTV: test glow plug resistance, check connectors, and confirm the control module is commanding pre-heat as expected.
• Petrol UR V8s: check each coil-on-plug for cracks, carbon tracking, or moisture, replace spark plugs per the maintenance schedule and re-seat coils carefully.

Does a 2014 Land Cruiser have ignition leads?
No. Diesel models have glow plugs rather than spark plugs, and petrol V8 models use coil-on-plug ignition. Toyota’s 200 Series workshop information and parts catalogues list individual ignition coils and spark plugs for petrol engines, and no high-tension lead set across the range.

What should be serviced instead of ignition leads on a 2014 Land Cruiser?
For diesel, focus on the glow plug system, battery health, and related wiring. For petrol, inspect each ignition coil and replace the iridium spark plugs at the interval in the service book. Coils and plugs are the real-world “ignition maintenance” items on these vehicles.

Can worn ignition leads cause a misfire on a 2014 Land Cruiser?
Not on this model, because it doesn’t use them. If there’s a misfire, common culprits are a tired coil, worn spark plug (petrol), injector issues, air leaks, or low compression. Diesel owners should also consider injector performance and glow system checks for hard cold starts rather than chasing leads that aren’t there.
