Ignition Coil and Iridium Spark Plugs for Mitsubishi Outlander (2014-2019) 2.4L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2014-2019 Mitsubishi Outlander

What it Does: The ignition coil and iridium spark plug kit restores secondary voltage delivery and combustion efficiency on the 2014-2019 Mitsubishi Outlander to eliminate misfires and restore lost fuel economy.

The Stock Mitsubishi Outlander Ignition Degradation

In the GF-series chassis, thermal cycling within the cylinder head recess degrades the factory coil-on-plug boots and epoxy insulation over time. Prolonged heat soak induces dielectric breakdown within the primary and secondary copper windings, precipitating micro-arcing, intermittent current leakage, and severe secondary voltage drop under load. Concurrently, factory standard or worn plugs suffer from enlarged electrode gaps due to spark erosion, escalating the required breakdown voltage. This overburdened condition triggers hesitation, rough idle, P0300–P0304 diagnostic trouble codes, and unburned fuel entering the catalytic converter.

The Engineering Solution

This complete service overhaul features four high-dielectric pencil ignition coils matched with fine-wire iridium spark plugs designed to match OEM impedance profiles. The coils utilize vacuum-impregnated magnetic epoxy resin and high-grade copper wire to isolate against electrical leakage and withstand intense thermal stress. Coupled with corrosion-resistant silicone elastomer boots, current tracks directly to the spark plug terminal without voltage loss. The fine-wire iridium center electrodes dramatically lower the required firing voltage, providing a stable, concentrated spark kernel across all rpm bands while offering superior resistance to carbon fouling and erosion.

Frequently Asked Questions

Does this fit the GF3W Outlander?
Yes, this is a direct fit for the 2014-2019 Mitsubishi Outlander equipped with the 4J12 2.4L engine.

Do the iridium spark plugs require gapping prior to installation?
No, these plugs come pre-gapped to factory specifications, and manual adjustment risks damaging the fine-wire iridium electrode.
