Parts for your 2016 Nissan Navara-Ignition leads

2016 Nissan Navara ignition leads — are they even a thing?

For the 2016 Nissan Navara (D23/NP300) sold in Australia and New Zealand, ignition leads aren’t fitted or required. The common engines for this model year are the 2.3‑litre turbo-diesels (YS23DDT and YS23DDTT). According to the Nissan Navara D23 workshop manual (Engine Control and Engine Mechanical sections) and the 2016 Owner’s Manual service schedule, these diesels use compression ignition with glow plugs and have no spark plugs or high‑tension leads. No ignition-leads appear as a service item in those factory publications.

In some overseas markets a 2.5‑litre petrol QR25DE was offered in the D23 generation. The Nissan service literature for the QR25DE shows a coil‑on‑plug (COP) ignition system, where each spark plug has its own ignition coil mounted directly on top. That setup eliminates traditional ignition leads, there are no long high‑tension cables, just short insulators integral to each coil.

• Diesel YS23 engines: compression ignition, glow plugs only, no spark system, no leads (Nissan D23 service manual – Glow Plug Control, EC section).
• Petrol QR25DE (where fitted): coil‑on‑plug design, no conventional HT leads (Nissan EC – Ignition System for QR25DE).

So, if a parts catalogue shows “ignition-leads” for a 2016 Navara, it’s either referencing older Navara generations (like D22/D40 petrols with distributor or remote coil packs) or it’s a generic listing. For a 2016 D23 diesel, there’s nothing to replace in that category.

What should owners look after instead? For the diesel, keep the glow plug system healthy, maintain a strong battery (vital for cold starts), and follow the service intervals for fuel and air filters. If sitting under the bonnet of a rare 2016 D23 petrol import, focus on spark plugs at the scheduled interval and check the coil-on-plug units for cracking, carbon tracking, or oil in the plug tubes. Dielectric grease on the coil boots can help future removal, but there are no leads to replace.

Bottom line: the 2016 Navara doesn’t use ignition leads. That’s by design—either because it’s a diesel with no spark ignition, or a COP petrol with coils sitting right on the plugs, both of which remove the need for traditional leads while improving reliability and emissions.

Popular questions about 2016 Nissan Navara ignition leads

Do 2016 Navara diesels have ignition leads?
No. The 2.3‑litre YS23 diesel engines use compression ignition and glow plugs, so there are no spark plugs or high‑tension leads. This is consistent with Nissan’s D23 service manual and the Owner’s Manual, which don’t list ignition components for routine service on diesel models.

What should be serviced instead of ignition leads on a 2016 diesel Navara?
Focus on fuel and air filters, glow plugs if starting becomes sluggish, and keep the battery and charging system in top nick. Clean air intake components and stick to quality diesel to protect injectors. These have a far bigger impact on starting and drivability than any “ignition” parts on a diesel.

I found ignition leads online for a 2016 Navara—will they fit?
Unlikely. Those listings often target older D22/D40 petrol models or use generic fitment data. The 2016 D23 diesels don’t use leads, and the occasional D23 petrol runs coil‑on‑plug with no conventional leads. Check the VIN and engine code, if it’s YS23, there are no leads to buy.
