Parts for your 2022 Toyota Land cruiser-Ignition leads

2022 Toyota Land Cruiser ignition leads: are they used, and do they need servicing?

For the 2022 Toyota Land Cruiser (300 Series), ignition leads aren’t a thing. The petrol 3.5‑litre twin‑turbo V6 (V35A‑FTS) runs a coil‑on‑plug Direct Ignition System, so there are no traditional high‑tension leads between a distributor and the spark plugs. The 3.3‑litre twin‑turbo V6 diesel (F33A‑FTV) doesn’t use spark ignition at all, it’s compression ignition and relies on glow plugs only for cold starts. This setup is confirmed in Toyota’s service literature for the V35A‑FTS Direct Ignition System (coil on plug with built‑in igniter) and diesel engine operation, as well as industry texts on modern ignition systems (e.g., Bosch Automotive Handbook) and Toyota Global Newsroom technical releases for the 300 Series.

Why no leads? Coil‑on‑plug puts an individual ignition coil directly over each spark plug, shortening the high‑voltage path and removing the need for separate leads. It improves spark energy, timing accuracy and reliability, especially under heat and vibration—perfect for a Land Cruiser that sees towing, corrugations and desert heat. On the diesel, there’s simply no spark circuit to begin with, so nothing to route.

What owners should look after instead depends on the engine fitted:

• Petrol V35A‑FTS: service the spark plugs at the interval in the maintenance schedule (iridium plugs typically have long life). Inspect the coil boots and plug tube seals for hardening or tracking, particularly after deep water crossings or heavy dust. If misfires pop up, scan for codes and test coils before assuming a plug issue. Keep oil out of the plug tubes and torque coils and plugs to spec.
• Diesel F33A‑FTV: there are no ignition components to maintain. Focus on fuel quality and filtration, correct glow plug operation, and scheduled services.

So, if someone’s chasing “ignition leads” for a 2022 Land Cruiser, they’ll come up empty. The design deliberately eliminates them—less to replace, fewer dramas, and better reliability out in the scrub. Technical sources supporting this include Toyota’s Repair/Workshop Manuals for the V35A‑FTS Direct Ignition System and F33A‑FTV engine operation, Toyota Global Newsroom product info for the 300 Series (noting the new V6 powertrains), and standard references on coil‑on‑plug ignition used across late‑model vehicles.

• Does a 2022 Toyota Land Cruiser have ignition leads?
  No. The petrol V35A‑FTS uses coil‑on‑plug ignition with no separate high‑tension leads, and the diesel F33A‑FTV is compression‑ignition with no spark system. This layout is documented in Toyota service materials and aligns with modern engine design.
• What should be serviced instead of ignition leads on the petrol V6?
  Stick to the scheduled spark plug replacement, and check the individual ignition coils, boots and seals—especially after water crossings or lots of dust. If there’s a misfire, scan it first, coils, plugs or a sealing issue are the usual suspects.
• Can ignition leads be fitted or retrofitted to a 2022 Land Cruiser?
  No. The engine architecture doesn’t use a distributor or remote coils, so there’s nowhere for leads to go. Any ignition servicing centres on the plugs and the coil‑on‑plug assemblies.
