Parts for your 2014 Mitsubishi Lancer-Ignition coils

2014 Mitsubishi Lancer ignition coils

Ignition coils are absolutely fitted to the 2014 Mitsubishi Lancer petrol models. Technical references back this up: the Mitsubishi CJ/CF service manual specifies a coil-on-plug setup for the 2.0L 4B11 and 2.4L 4B12 engines, the Mitsubishi ASA parts catalogue lists the ignition coil assemblies (e.g. 1832A123) for these engines, and major aftermarket catalogues from NGK and DENSO carry direct-fit coils for the 2014 Lancer. Note for completeness: some overseas Lancers were sold with a diesel, those use glow plugs and don’t run ignition coils, but petrol models common to Australia and New Zealand do.

On a 2014 Lancer, each cylinder gets its own coil-on-plug unit. The job’s simple but critical: the coil steps up battery voltage and fires the spark plug right when the ECU commands it, so the engine starts crisply, idles smoothly, and pulls cleanly through the revs. When a coil weakens, drivers might notice a hiccup under load, rough idle, hard starts, higher fuel use, or the check engine light with codes like P0300–P0304 or P0351–P0354.

There’s no fixed replacement interval for coils, but they’re often inspected whenever spark plugs are serviced (typically around 100,000 km on the iridium-plug Lancer). Smart servicing includes checking for cracked housings, heat-baked boots, oil in the plug tubes from a cam cover gasket seep, and loose connectors. If oil is present, sort the gasket first or the new coils may fail early.

Swapping a coil is a straightforward bonnet-up job: disconnect the battery, remove the engine cover, unplug the connector, pull the coil, and refit the new one. A dab of dielectric grease on the boot helps future removal and sealing. The small hold-down bolt only needs light torque (around 8–10 N·m), so don’t swing off it. When one coil dies at high kilometres, some owners proactively replace the set to save repeat labour, but it’s fine to replace just the faulty unit and keep the others as long as they test well.

Use quality, correct-spec coils to match the 4B11/4B12, and pair them with the right plugs and proper plug gaps. After fitting, clear any fault codes and take a test drive to confirm a smooth idle and clean acceleration. Look after the coils and plug seals, and the Lancer’s petrol engine will stay happy for the long haul.

• Watch for misfire under load, rough idle, hard starts, higher fuel use.
• Inspect coils whenever spark plugs are serviced, fix any oil leaks first.
• Torque lightly and use dielectric grease on boots when refitting.

Popular questions about 2014 Mitsubishi Lancer ignition coils

How often should the ignition coils be replaced on a 2014 Lancer?

They’re not a routine replacement item like oil or filters. Many last well past 150,000 km. Inspect them at each plug change or if a misfire pops up. Replace only when faulty, or consider a full set if multiple coils are ageing and the vehicle has high kilometres.

What are the common symptoms of a bad ignition coil on this model?

Typical signs are a flashing or steady check engine light, rough idle, stumble under load, slow or hard starts, and higher fuel use. Scan tools often show misfire codes (P0300–P0304) or a specific coil circuit code (P0351–P0354). If the issue appears mainly when it’s wet, check for cracked boots or water in the plug wells.

Can you drive a 2014 Lancer with a failing coil?

It might run, but it’s not a great idea. Ongoing misfires can overheat and damage the catalytic converter and may wash fuel into the oil. If it’s a light stumble, drive gently to a workshop, if it’s severe or the check engine light is flashing, it’s best to park it and organise a tow.
