Parts for your 2024 Mitsubishi Eclipse cross-Ignition coils

2024 Mitsubishi Eclipse Cross Ignition Coils

Ignition coils are absolutely used on the 2024 Mitsubishi Eclipse Cross. Mitsubishi’s workshop information for the 1.5L turbo petrol (4B40) and the Eclipse Cross PHEV’s 2.4L petrol engine specifies a direct ignition, coil‑on‑plug system, and the official Mitsubishi parts catalog lists an individual ignition coil for each cylinder. That means ignition coils are relevant for every 2024 Eclipse Cross variant sold in Australia and New Zealand.

In this model, each coil sits directly on top of its spark plug. Its job is to step up the 12‑volt battery supply into the thousands of volts needed to jump the plug gap and ignite the air–fuel mix. Coil‑on‑plug keeps things tidy under the bonnet, reduces energy losses compared with old‑school leads, and gives the engine control unit finer command over timing and spark intensity for better performance and economy.

They aren’t a routine “replace on schedule” item, but they do work hard and can age. Owners can expect long service life if the right spark plugs are used and changed on time. When servicing a 2024 Eclipse Cross, it pays to:

• Replace spark plugs at the interval in the service book (often around the 90,000–120,000 km mark for iridium types) and use the correct spec and gap.
• Inspect coil boots for cracks, carbon tracking or oil intrusion, renew boots if they’re tired.
• Keep moisture out of the plug wells, avoid aggressive engine‑bay washing.
• Use a small dab of dielectric grease on the boot to help sealing and future removal.
• Torque coil hold‑downs to the workshop spec and clip loom connectors securely.

Common signs a coil is on the way out include a rough idle, hesitation on load, reduced fuel economy, hard starts, and a flashing check‑engine light with misfire codes (P0300–P030X). If one fails at higher kilometres, many techs recommend replacing the affected coil and its spark plug together, on older, high‑km engines, doing the full set can save repeat visits.

For PHEV models, coil and plug work is on the petrol engine side, standard 12‑volt battery precautions apply. Ensure the hybrid system is off, give the engine time to cool, and disconnect the 12‑volt negative terminal if removing coils. A quick post‑repair road test and scan to clear any stored fault codes finishes the job nicely.

How often should ignition coils be replaced on a 2024 Eclipse Cross?

There’s no fixed replacement interval, coils are replaced on condition. With correct iridium plugs and tidy servicing, they often last well past 150,000 km. If misfire symptoms or fault codes point to a specific coil, test and replace that unit, and fit a fresh plug at the same time.

Is it safe to keep driving with a suspected bad coil?

Best not. Driving with a misfire can wash fuel into the exhaust, overheat the catalytic converter, and bump up fuel use. If the check‑engine light is flashing or the engine feels rough, ease off and get it checked promptly.

Should coils be replaced as a full set?

If one coil fails at low kilometres, replacing just that coil is fine. On higher‑km vehicles, doing the full set can be cost‑effective, especially if access is fiddly. Always pair the job with the correct new spark plugs and inspect the boots and connectors.
