Ignition Coil and Iridium Spark Plugs for Kia Soul (2012-2019) 1.6L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2012-2019 Kia Soul

What it Does: Restores factory ignition energy, stabilizes erratic idle, and eliminates high-rpm misfires by replacing degraded coil-on-plug packs and worn spark plugs with matched direct-fit components.

The Stock Soul Secondary Ignition Breakdown

The Gamma 1.6L GDI engine operates under high cylinder pressures and elevated thermal cycles within a compact engine bay. Over sustained heat cycles, the factory epoxy resin around the internal coil windings degrades, allowing micro-fractures to form. These thermal stress cracks cause dielectric breakdown, leading to intermittent secondary voltage leaks, carbon tracking along the plug boot, premature electrode erosion on standard plugs, and rough idle under load.

The Engineering Solution

This ignition service pack features four heavy-duty coil-on-plug assemblies engineered with high-conductivity copper windings and heat-resistant silicone boots to isolate against dielectric puncture. Matched with four fine-wire iridium spark plugs, this setup lowers required firing voltage, accelerates flame-front propagation, and resists carbon fouling under direct-injection operating conditions. Factory-molded blade connectors ensure a direct mechanical and electrical connection without harness modification.
