Parts for your 2020 Mitsubishi Eclipse cross-Ignition leads

2020 Mitsubishi Eclipse Cross ignition leads — are they used?

For the 2020 Mitsubishi Eclipse Cross, traditional ignition leads (high-tension spark plug wires) are not fitted or required. Technical documentation such as the Mitsubishi Motors service manual for the GK-series Eclipse Cross (1.5L 4B40 MIVEC turbo petrol) specifies a coil-on-plug ignition system, where each cylinder has its own pencil-style ignition coil mounted directly on the spark plug. Mitsubishi’s ASA parts catalogue for the same vehicle lists individual ignition coils and spark plugs, with no “high-tension cord” or distributor components. The owner’s handbook also refers to long-life iridium plugs and does not outline any spark plug lead maintenance.

This coil-on-plug (COP) setup replaces the old-school distributor-and-leads arrangement. By firing the spark directly at the plug, COP reduces energy losses, improves spark accuracy, and helps the engine meet tighter emissions standards. It also cuts down on electromagnetic interference and misfire risk, which is especially handy on a compact turbo engine where packaging under the bonnet is tight. Fewer moving and high-voltage parts means fewer things to service or replace over time.

What should owners look after instead? While there are no ignition leads to worry about, the Eclipse Cross still relies on quality plugs and healthy coils. As part of routine servicing:

• Replace spark plugs at the interval specified in the service schedule (often around the long-life mark for iridium plugs).
• Inspect each ignition coil and its rubber boot for cracking, tracking marks, oil contamination in the plug tubes, or moisture.
• If a Check Engine light pops up with misfire codes (e.g., P0300–P0304), test the suspect coil and plug before replacement.
• When refitting plugs, use the torque and gap specs from the service manual and consider a small dab of dielectric grease inside the coil boots.

It’s worth noting that all 2020 petrol Eclipse Cross variants use COP, so there’s genuinely no ignition-lead maintenance to perform. And for regions that offered diesel trims, those engines don’t use spark plugs at all, further confirming why ignition leads aren’t a thing on this model year.

Popular questions

Does the 2020 Eclipse Cross have ignition leads I need to replace?
No. It uses coil-on-plug ignition with individual coils sitting directly on each spark plug, so there are no traditional high-tension leads to service or swap. Maintenance focuses on spark plugs and inspecting the coils and their boots.

What should be serviced in the ignition system on a 2020 Eclipse Cross?
Follow the schedule for the iridium spark plugs and periodically check each coil for damage or contamination. If there’s a misfire or rough running, scan for fault codes, then test or replace the affected plug and/or coil as needed.

Why did Mitsubishi drop ignition leads on this model?
Coil-on-plug delivers a stronger, more precise spark, improves reliability, reduces electrical losses, and helps with emissions and packaging—ideal for the turbocharged 1.5L layout. Fewer parts also means less ongoing maintenance for owners.
