Parts for your 2013 Mitsubishi Lancer-Ignition coils

2013 Mitsubishi Lancer Ignition Coils

Technical sources including the Mitsubishi Motors Lancer CJ/CF Service Manual (Engine Electrical, Group 16) and the Mitsubishi ASA parts catalogue show the 2013 Lancer petrol engines (such as the 2.0L 4B11, 2.4L 4B12 and 4B11T turbo) are fitted with individual coil-on-plug ignition coils, one per cylinder. Some markets also offered a 1.8 Di‑D diesel (4N1 series) that uses compression ignition and glow plugs, not ignition coils. For most Australian and New Zealand 2013 Lancers, which are petrol, ignition coils are relevant service items.

The ignition coil’s job is simple but crucial: it steps up the 12‑volt battery supply to tens of thousands of volts so the spark plug can fire cleanly under all loads. On the 2013 Lancer’s petrol engines, each cylinder gets its own coil perched directly on the spark plug. That design improves spark energy, trims emissions and helps the engine run smoother and more efficiently.

Coils aren’t a scheduled replacement item like oil or filters, but they do age from heat and vibration. As part of routine servicing, it’s smart to:

• Inspect the coil boots for cracking, hardening or carbon tracking.
• Check the plug wells for oil, if present, sort the rocker cover gasket before fitting new coils or plugs.
• Replace spark plugs at the recommended interval so coils aren’t overworked trying to fire worn plugs.
• Use a dab of dielectric grease inside the boot to help sealing and future removal.

Common signs a coil’s on the way out include a rough idle, hesitation under load, poor fuel economy, and a check engine light—often logging misfire codes like P0300–P0304. A quick way to confirm is to swap the suspect coil to another cylinder and see if the misfire follows. When replacing, go with quality OEM‑equivalent parts and follow workshop guidance for connector handling and fastener torque, don’t overtighten the small coil hold‑downs. After installation, clear any stored codes and take a short drive to confirm the fix.

Looked after this way, many Lancer coils will run well past 150,000 km. If one fails at high kilometres, it can be worth replacing the full set to keep the engine feeling even and to avoid repeat visits.

Popular questions about 2013 Mitsubishi Lancer ignition coils

How can someone tell if a Lancer ignition coil is failing?
They’ll usually notice a stumble at idle, a flat spot when accelerating, or the check engine light popping up with a misfire code. If the fault moves when the coil is swapped to another cylinder, that’s a solid clue the coil is the culprit.

How often should ignition coils be replaced on a 2013 Lancer?
There’s no fixed interval. They’re replaced when symptoms appear or inspection shows damage. Keeping fresh spark plugs in and the plug wells clean helps coils last longer.

Can a bad ignition coil damage other parts?
Yes. Persistent misfires can overheat and damage the catalytic converter and may foul the spark plug. It’s worth diagnosing and sorting a misfire promptly.
