Ignition Coil and Iridium Spark Plugs for Mitsubishi Outlander Sport (2016-2017) 2.4L

Direct-Replacement Ignition Kit for 2016-2017 Mitsubishi Outlander Sport

What it Does: Restores factory secondary ignition output by replacing deteriorated coil packs and worn plugs with matched copper-wound ignition coils and fine-wire iridium spark plugs.

The Stock Outlander Sport Ignition Breakdown

The 4B12 2.4L engine subjects ignition components to severe underhood thermal cycling and dielectric breakdown. Over time, factory coil insulation degrades, allowing secondary voltage leakages, carbon tracking, and internal winding short-circuits. Combined with electrode erosion on aging spark plugs, this causes increased secondary resistance, intermittent misfires under load, sluggish throttle response, and rough idle conditions.

The Engineering Solution

This comprehensive service kit includes four high-dielectric ignition coils built with premium internal copper windings and corrosion-resistant blade terminals, paired with four long-life iridium spark plugs. The fine-wire iridium design lowers required firing voltage, optimizing arc stability under varying compression loads while resisting electrode erosion and fouling to restore clean combustion efficiency.
