Ignition Coil and Iridium Spark Plugs for Hyundai Kona (2018-2021) 2.0L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2018-2021 Hyundai Kona

What it Does: Restores factory ignition energy, eliminates primary misfires, and stabilizes combustion cycles across the 2.0L Atkinson-cycle powertrain.

The Stock Kona Ignition Coil and Plug Degradation

Factory ignition assemblies on the Nu 2.0L engine endure intense thermal cycles within the compact engine bay, causing dielectric breakdown in internal epoxy potting and degradation of the secondary copper windings. Over time, standard spark plug electrode erosion widens the gap, demanding higher ionization voltage from aging coils. This thermal and electrical fatigue leads to internal resistance spikes, spark blow-out under throttle tip-in, rough idle vibration, and P0300-series misfire trouble codes.

The Engineering Solution

This complete tune-up kit restores cylinder efficiency by pairing precision-wound direct-fit ignition coils with fine-wire iridium spark plugs. The coil-on-plug assemblies feature high-grade magnetic copper windings, heat-resistant silicone boots, and durable thermoplastic housings to withstand dielectric stress. Coupled with iridium center electrodes, this package delivers consistent spark kernel development, reduces required strike voltage, and ensures stable combustion under all operating loads.
