Parts for your 2023 Mitsubishi Eclipse cross-Ignition coils

2023 Mitsubishi Eclipse Cross ignition coils

Ignition coils are fitted to the 2023 Mitsubishi Eclipse Cross. Technical references including Mitsubishi Motors service information, the Mitsubishi dealer parts catalogue (ASA), and reputable aftermarket data sets (Autodata/AllData, NGK/Delphi application guides) list coil-on-plug ignition coils for both the 1.5‑litre MIVEC turbo petrol and the Eclipse Cross Plug‑in Hybrid’s 2.4‑litre petrol engine. Each cylinder uses its own plug‑top coil, so ignition coils are absolutely relevant for this model.

On this Eclipse Cross, the ignition coils transform the 12‑volt supply into the high voltage needed to fire the spark plugs, lighting the fuel‑air mix cleanly in each cylinder. Because they’re coil‑on‑plug, there are no old‑school leads to worry about, which helps with reliability and a strong, consistent spark under load.

They’re generally not a scheduled replacement item, but they do benefit from a bit of attention during regular servicing. Any time the spark plugs are replaced (typically around the 90–100,000 km mark depending on market schedule and plug type), it’s worth pulling the coils to check the boots for carbon tracking, oil or moisture in the plug tubes, and any cracking of the housings. Keeping the plug wells clean and dry, and avoiding blasting the area with a pressure washer under the bonnet, goes a long way toward coil longevity.

Common clues that a coil is on the way out include a rough idle, hesitation on hills, higher fuel use, hard starting when cold, and a glowing check‑engine light. Scan tools often show misfire counts or codes like P0300–P0304, or coil circuit faults (P0351–P0354). If those pop up, rule out worn plugs first, as tired plugs can make a good coil look bad.

When replacement is needed, quality matters. Genuine Mitsubishi or reputable aftermarket coils that meet OE spec are the smart pick. Some owners choose to replace a single failed coil and carry on, others replace the full set if the vehicle’s done higher kilometres to keep things even. Either way, fitting is straightforward: disconnect the connector, remove the small retaining bolt, lift the coil, swap the plug if required, then refit the coil and torque the fasteners correctly. A tiny smear of dielectric grease on the boot helps future removal and seals out moisture. After refitting, clear codes and road‑test to confirm a smooth, clean pull through the rev range.

• Watch for misfire codes and rough running under load.
• Inspect coils whenever plugs are changed.
• Keep water and oil out of plug wells to protect the boots.

Popular questions about 2023 Mitsubishi Eclipse Cross ignition coils

How long do the ignition coils typically last?
On most Eclipse Cross vehicles, coils often run well past 150,000 km. Life varies with heat, plug condition, and moisture exposure. If the engine is serviced on time and plug wells stay clean and dry, the coils generally last many years without fuss.

What are the signs an ignition coil is failing?
Drivers usually notice a shaky idle, flat spots on acceleration, poorer fuel economy, or a check‑engine light. A scan may show P0300–P0304 misfires or P0351–P0354 coil circuit faults. Always check plug condition first, as worn plugs can mimic coil problems.

Should all four coils be replaced at once?
It’s acceptable to replace only the failed coil, especially on lower‑kilometre cars. If the vehicle has covered high kilometres or multiple coils have failed in short order, replacing the full set can save repeat labour and keep performance consistent across cylinders.
