Parts for your 2016 Mitsubishi Lancer-Ignition coils

2016 Mitsubishi Lancer ignition coils

Ignition coils are absolutely used on the 2016 Mitsubishi Lancer. Technical references including the Mitsubishi Lancer service manual (2008–2017 platform, Engine Electrical/Group 16), Mitsubishi parts catalogues, and application data from NGK and DENSO confirm the 2.0L (4B11) and 2.4L (4B12) MIVEC petrol engines run a coil-on-plug setup with one ignition coil per cylinder.

On this Lancer, each ignition coil’s job is to step the 12V battery supply up to the high voltage needed to fire the spark plug cleanly. Being coil-on-plug, there are no traditional high-tension leads, the coil sits directly over each spark plug under the bonnet. That design improves spark energy, reduces electrical losses, and helps the car start crisply and run smoothly day to day.

While ignition coils aren’t a scheduled replacement item, they live in a hot environment and can tire over time. As part of routine servicing, it’s smart to inspect the coils whenever the spark plugs are changed (typically every 90,000–100,000 km for iridium plugs, per common service practice). Look for cracked boots, heat damage, or any oil in the plug wells (often from a cam cover gasket seep). Keep the area clean and dry—moisture and oil contamination are enemies of coil insulation.

Tell-tale signs a coil may be playing up include:

• Rough idle, hesitation under load, or poor fuel economy
• Check engine light with misfire codes (e.g., P0300–P0304)
• Hard starting or a raw fuel smell from unburnt petrol in the exhaust

Diagnosis is straightforward: scan for fault codes and live misfire data, then perform a quick “swap test” by moving a suspect coil to another cylinder to see if the misfire follows. Because modern coils are solid-state, resistance checks aren’t very conclusive.

Replacement is a simple DIY for many owners: disconnect the battery, pop off the engine cover, unplug the connector, remove the small hold-down bolt, then lift the coil straight out. Fit the new coil, apply a smear of dielectric grease to the boot (not the electrical pins), seat it firmly, and torque the hold-down bolt to around 8–10 N·m. Ensure the connector clicks home. If more than one coil is weak, replacing them as a set can save time and headaches. After fitting, clear any codes and road test to confirm a smooth, clean pull through the revs.

Quality matters here—stick with genuine or reputable brands matched to the 4B11/4B12 engines for the best reliability and spark performance.

Popular questions about 2016 Mitsubishi Lancer ignition coils

How long do ignition coils typically last on a 2016 Lancer?
Many last well past 150,000 km, but heat and vibration eventually take a toll. If the car is serviced regularly, spark plugs are kept fresh, and plug wells stay clean and dry, coils tend to go the distance. Replace any coil that shows consistent misfire under load or triggers repeated cylinder-specific codes.

Should coils be replaced when changing spark plugs?
Not automatically. Coils aren’t a consumable like plugs. Inspect them at each plug change, if the boots are cracked, there’s oil contamination, or you’ve had intermittent misfires, it’s sensible to replace affected coils then. Otherwise, refit them and recheck performance.

Are aftermarket coils OK for the 2016 Lancer?
Yes—provided they meet OEM specifications for the 4B11/4B12 engines. Choose reputable brands (the same names that supply OEM) to ensure proper dwell, output voltage, and connector fit. Ultra-cheap options can cause weak spark, radio interference, or short service life.
