Parts for your 2014 Mitsubishi Asx-Ignition leads

2014 Mitsubishi ASX ignition leads — what’s actually fitted

For the 2014 Mitsubishi ASX, traditional ignition leads (high‑tension spark plug wires) aren’t used. All petrol variants in this model year run a coil‑on‑plug (COP) ignition system, where an individual ignition coil sits directly on top of each spark plug under the bonnet. The diesel variant doesn’t use spark plugs at all, so it naturally has no ignition leads either.

This setup is confirmed by technical references: the Mitsubishi Motors ASX/RVR/Outlander Sport service manual (Engine Electrical/ Ignition System) specifies a direct‑ignition, coil‑on‑plug arrangement, the Mitsubishi ASA parts catalogue lists individual ignition coils and spark plugs but no HT lead set, and aftermarket catalogues from NGK and Bosch list COP ignition coils for the 2014 ASX and note the absence of ignition cables. Trade data services such as Autodata/Haynes also detail COP across the 1.6L 4A92 and 2.0L 4B11 petrol engines used in the ASX around 2014.

Why no ignition leads? COP improves spark energy and timing accuracy, reduces electrical losses, and cuts down on misfire risk from ageing leads. Fewer components means fewer wear points and better reliability in day‑to‑day Kiwi and Aussie driving.

• Petrol ASX (1.6/2.0): Uses coil‑on‑plug, so no separate ignition leads to replace.
• Diesel ASX: Compression ignition, no spark plugs, no ignition leads.

What should owners service instead? Focus on spark plugs and the coils themselves. Stick to the service schedule for plug replacement (often around 90,000–100,000 km for iridium, but always follow the vehicle’s maintenance guide). If there’s a rough idle, hesitation, or a check‑engine light with a misfire code, a failing coil or worn plug is far more likely than a “lead” issue on this model. When removing coils, keep the boots clean and dry, check for cracking or oil contamination in the plug tubes, and refit with the correct torque on the plugs. There’s no separate lead set to maintain, so servicing is a bit simpler and tidier.

Bottom line: ignition leads aren’t relevant to the 2014 Mitsubishi ASX because of its coil‑on‑plug (petrol) and compression‑ignition (diesel) designs. Owners and workshops should direct attention to good‑quality plugs, healthy coils, and up‑to‑date engine software and maintenance.

• Does a 2014 Mitsubishi ASX have ignition leads?
  No. Petrol models use coil‑on‑plug ignition, and diesel models don’t use spark plugs at all. There’s no separate HT lead set on this vehicle.
• What should be serviced instead of ignition leads on a 2014 ASX?
  Replace spark plugs at the recommended interval and inspect the individual ignition coils if there are misfire symptoms. Keep plug tubes clean and dry to protect the coils.
• Can ignition leads be fitted to a 2014 ASX as an upgrade?
  Not practically. The engine is designed for coil‑on‑plug, there’s no performance or reliability gain in trying to retrofit leads. Use quality plugs and coils for best results.
