Parts for your 2019 Mitsubishi Eclipse cross-Ignition coils

2019 Mitsubishi Eclipse Cross Ignition Coils: Purpose, Care, and When to Replace

Ignition coils are absolutely relevant and fitted to the 2019 Mitsubishi Eclipse Cross. Technical sources including the Mitsubishi Motors Eclipse Cross (GK/GL) workshop manual for the 4B40 1.5L MIVEC turbo engine (Engine Electrical – Ignition System) specify a coil-on-plug setup: four individual ignition coils, one per cylinder. Major aftermarket catalogues used by workshops in Australia and New Zealand also list direct-replacement coils for this model year and engine, confirming their use.

In this Eclipse Cross, the ignition-coils sit directly on top of each spark plug. Their job is to step up the 12-volt battery supply into the high voltage needed to fire the plugs cleanly under all loads and revs. Coil-on-plug design cuts out traditional high-tension leads, improving reliability and spark accuracy—handy for a modern, direct-injected turbo four.

As part of routine servicing of your 2019 Mitsubishi Eclipse Cross ignition-coils, a tech will usually check for cracking, carbon tracking, heat discolouration, loose connectors, and oil or moisture in the plug wells. There’s no strict replacement interval for coils, they’re replaced when symptoms point to a fault. Common signs include rough idle, hesitation under load, poor fuel economy, harder starting, and a glowing check engine light. Scan tools often show misfire codes like P0300–P0304. A quick workshop trick is to swap the suspect coil to another cylinder to see if the misfire follows.

When replacing coils, sticking with genuine or high-quality aftermarket units is wise. It’s also smart to inspect or replace spark plugs at the same time—tired plugs can overwork new coils. Keep the coil boots clean, use a small dab of dielectric grease on the inside lip of the boot, and make sure connectors click firmly home under the bonnet. Avoid pressure-washing the engine bay, as trapped moisture in the plug tubes can knock coils around. If the vehicle has racked up higher kilometres or has had repeat coil faults, some owners choose to replace the full set for peace of mind.

For day-to-day care, scheduling regular inspections (especially from 60,000 km onward) and addressing any oil leaks at the rocker cover will help protect the coils and keep the Eclipse Cross running sweet as.

• Number of coils: 4 (coil-on-plug)
• Typical fault clues: misfire, rough idle, check engine light
• Good practice: inspect with plug service, keep moisture and oil out of plug wells

Popular questions about 2019 Mitsubishi Eclipse Cross ignition-coils

How many ignition coils does the 2019 Eclipse Cross have?
It runs a coil-on-plug setup with four individual coils—one per cylinder. This design improves spark control and reliability by eliminating traditional high-tension leads.

What are the symptoms of a failing ignition coil on this model?
Expect a rough idle, stumbling under load, poorer fuel use, and the check engine light. A scan may reveal misfire codes like P0301–P0304. If the fault moves when coils are swapped between cylinders, that coil’s the culprit.

Should all coils be replaced at once?
Not always. It’s fine to replace only the failed unit after proper diagnosis. If the car has high kilometres or multiple coils are playing up, many owners opt to change the full set to restore consistency and avoid repeat visits.
