Parts for your 2016 Mitsubishi Asx-Ignition coils

2016 Mitsubishi ASX ignition coils

Based on Mitsubishi technical references, ignition coils are relevant to the 2016 Mitsubishi ASX when it’s fitted with a petrol engine. The Mitsubishi Motors ASX/RVR/Outlander Sport workshop manual (2015–2017, Group 16: Ignition) specifies a coil‑on‑plug system for the 2.0‑litre MIVEC petrol engines (4B11/4J11), and the Mitsubishi ASA electronic parts catalogue lists individual ignition coil assemblies for these models. By contrast, the 2.2 Di‑D diesel (4N14) uses compression ignition and therefore has no spark plugs or ignition coils, as outlined in the Mitsubishi 4N1 series engine workshop manual.

For petrol 2016 ASX models, the ignition coils sit directly on top of the spark plugs under the bonnet. Their job is to step up the battery’s 12 volts to the thousands of volts needed to jump the spark plug gap and ignite the air‑fuel mix. With one coil per cylinder, the ASX gets precise, reliable spark timing, better cold starts, and smoother running.

Coils aren’t a regular replacement item like filters, but they do age. Heat, vibration, oil in the plug wells, or worn spark plugs can stress them. Common signs a coil is on the way out include a rough idle, sluggish take‑off, increased fuel use, a flashing or steady check engine light, and a noticeable misfire under load or up a hill.

Good servicing habits help coils last. When the ASX has its scheduled spark plug change (often around the 90,000–100,000 km mark for iridium plugs, follow the owner’s handbook), it’s smart to inspect the coils and boots for cracks, carbon tracking, or corrosion. Ensure the plug wells are dry and free of oil—if there’s oil, a rocker cover gasket may need attention. Using quality OEM‑spec plugs and coils (Mitsubishi/Denso spec) maintains the correct resistance and heat range, which keeps the coils happier. A dab of dielectric grease inside the coil boot can help sealing and future removal.

If a coil fails, replacement is straightforward for a competent home mechanic: remove the engine cover, unplug the connector, undo the small hold‑down bolt, and lift the coil out. Refit in reverse, taking care with the connector and bolt torque as per workshop specs. Many owners replace coils individually when they fail, if the vehicle has high kilometres and multiple misfires, changing the set can save repeat labour. Avoid extended driving with a misfire—it can overheat the catalytic converter. When in doubt, a scan with a proper diagnostic tool will pinpoint the offending cylinder and confirm whether the coil is at fault.

• Petrol ASX (2.0 MIVEC): uses four coil‑on‑plug ignition coils.
• Diesel ASX (2.2 Di‑D): no ignition coils by design.

Popular questions about 2016 Mitsubishi ASX ignition coils

Does a 2016 Mitsubishi ASX have ignition coils?
Yes, if it’s the petrol 2.0‑litre MIVEC, it uses four coil‑on‑plug units—one per cylinder. The diesel 2.2 Di‑D variant doesn’t use ignition coils because it’s a compression‑ignition engine with no spark plugs.

How often should ignition coils be replaced on a 2016 ASX?
There’s no fixed interval. Coils are replaced when they fail testing or show symptoms such as misfires or a check engine light. Inspect them whenever spark plugs are changed, keep oil and moisture out of the plug wells, and expect well‑looked‑after coils to last well past 150,000 km.

Is it safe to drive with a failing ignition coil?
It might run, but it’s not recommended. Ongoing misfires can damage the catalytic converter, waste fuel, and leave the ASX down on power. If a misfire starts, organise a prompt diagnosis and repair to avoid bigger bills.
