Parts for your 2022 Nissan X-trail-Ignition leads

2022 Nissan X‑TRAIL ignition leads — what’s actually fitted

For the 2022 Nissan X‑TRAIL (T32 series) sold in Australia and New Zealand, traditional ignition leads aren’t used. Nissan specifies a coil‑on‑plug (COP) ignition system on its petrol engines (such as the 2.5‑litre QR25DE, and in some markets the MR20DD), where an individual ignition coil sits directly on top of each spark plug. This layout is detailed in the Nissan X‑TRAIL T32 Factory Service Manual (Engine Control and Engine Mechanical sections, “Ignition System/Coil‑on‑Plug”), and is reflected in OEM and aftermarket catalogues (Nissan electronic parts catalogues, plus NGK and Bosch application guides) which list coils and spark plugs but no high‑tension lead sets for this model. Diesel variants do not use spark ignition at all, so they also don’t have ignition leads.

Why no ignition leads? With COP, the high voltage is generated right at the plug, so there’s no need for long high‑tension cables. That cuts electrical losses and misfire risk, improves combustion stability, and reduces routine maintenance. The only “leads” present are low‑voltage wiring to each coil via the engine harness.

What should owners look after instead? For petrol X‑TRAILs, servicing focuses on spark plugs and the condition of the coil packs and plug boots:

• Spark plugs: replace at the interval specified in the maintenance schedule (commonly around the 100,000–120,000 km mark for long‑life iridium/platinum types). Use the correct heat range and gap as per the service manual.
• Coils and boots: if there’s a misfire, hard start, rough idle or a P03xx code, inspect coils for cracking, signs of arcing, or oil in the plug tubes. Lightly apply dielectric grease to the inside of boots on reassembly.
• Handling: avoid spraying high‑pressure water over the coil tops and connectors. When removing coils, release the connector lock first and lift straight up to prevent damage.
• Diagnostics: a scan tool showing consistent misfire counts on a single cylinder is a common pointer to a weak coil or worn plug. Swap‑testing coils between cylinders can help confirm the fault.

Popular questions about 2022 Nissan X‑TRAIL ignition leads

Does the 2022 X‑TRAIL have ignition leads?
No. The 2022 X‑TRAIL uses a coil‑on‑plug system, so there are no traditional high‑tension leads. Each cylinder has its own coil mounted directly on the spark plug, as outlined in Nissan’s T32 service documentation and parts listings.

What should be serviced instead of ignition leads on a 2022 X‑TRAIL?
For petrol models, focus on spark plug replacement at the scheduled interval and checking the condition of the individual ignition coils and boots. If there’s a misfire, these are the first places to look.

Can a failing coil mimic a bad lead on older cars?
Yep. Symptoms like rough idle, hesitation, or a single‑cylinder misfire can feel similar to old lead issues. On the X‑TRAIL, that’s typically a worn spark plug or a weak coil, not a lead. A quick scan and swap‑test of coils usually narrows it down.
