Parts for your 2015 Mitsubishi Outlander-Ignition leads

2015 Mitsubishi Outlander ignition leads – are they even a thing?

For the 2015 Mitsubishi Outlander, traditional ignition leads (high-tension spark plug wires) aren’t fitted or used. The petrol engines in this model range use a coil-on-plug (COP) ignition system, where an individual “pencil” ignition coil sits directly on top of each spark plug. The diesel variant doesn’t use spark ignition at all, so it has no ignition leads either. This applies across common 2015 Outlander engines sold in Australia and New Zealand, including the 2.0L (4B11), 2.4L (4B12), the 3.0L V6 (6B31), and the 2.2L diesel (4N14). The Outlander PHEV also uses COP on its petrol engine.

Technical references that confirm this include: the Mitsubishi Motors Outlander ZJ/ZK Service Manual (2013–2017), which describes a direct ignition (COP) setup in Group 13A Ignition System for the 4B11/4B12 and individual coils on the 6B31, the diesel section notes compression ignition with glow plugs only. Major parts catalogues for AU/NZ (e.g., OEM Mitsubishi ASA/CAPS, NGK AU/NZ, and Bosch eCat) list individual ignition coils and spark plugs for 2015 Outlander engines, but no high-tension lead sets—another clear indicator that traditional ignition leads are not used on this model year.

Why ditch the leads? COP improves spark energy at the plug, reduces electrical losses, helps emissions and fuel economy, and cuts down on components that wear. It’s also tidier under the bonnet. For owners, that means there’s no lead set to replace as part of routine servicing. Instead, the focus is on installing the correct spark plugs at the scheduled interval (often around 90,000–100,000 km for iridium types, but always check the vehicle’s service schedule), and inspecting the ignition coils and plug tube seals for cracking, carbon tracking or oil contamination from rocker cover gasket leaks. Keeping moisture out of the plug wells and using quality coils when replacement is needed will keep misfires at bay.

So, if someone’s shopping for “ignition leads” for a 2015 Outlander, they can scratch that off the list. The right maintenance targets are spark plugs, the individual coil packs, and—on diesels—glow plug health.

• Petrol models: coil-on-plug, no ignition leads
• Diesel models: no spark system, uses glow plugs
• Service focus: correct plugs, coil condition, no oil or moisture in plug tubes

Popular questions about 2015 Mitsubishi Outlander ignition leads

Does a 2015 Mitsubishi Outlander have ignition leads?
No. Petrol engines use coil-on-plug ignition with an individual coil per cylinder, and the diesel uses compression ignition with glow plugs. Factory manuals for the ZJ/ZK series and AU/NZ parts catalogues list coils and plugs, but no HT lead sets.

What should be serviced instead of ignition leads on a 2015 Outlander?
Stick to the service schedule for spark plugs (typically around 90,000–100,000 km for iridium plugs, check the handbook). Inspect the pencil coils and plug tube seals for cracking, carbon tracking or oil. If there’s a misfire, scan for codes and test coils before replacing parts.

Which 2015 Outlander engines use coil-on-plug?
The 2.0L (4B11), 2.4L (4B12) and 3.0L V6 (6B31) petrol engines all use coil-on-plug. The 2.2L diesel (4N14) doesn’t have a spark ignition system at all, relying on glow plugs for cold starts. The PHEV’s petrol engine is also coil-on-plug.
