Ignition Coil and Iridium Spark Plugs for Hyundai Elantra (2017-2020) 1.6L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2017-2020 Hyundai Elantra

What it Does: Replaces degrading factory ignition coils and worn plugs to eliminate high-load misfires and restore direct-injection combustion efficiency across the entire RPM band.

The Stock Elantra Ignition Breakdown

Under sustained boost and high cylinder pressures, the direct-injected 1.6L turbocharged Gamma engine generates significant cylinder head thermal loads. Factory coil packs frequently suffer dielectric breakdown as internal epoxy degrades from thermal cycling. This leads to secondary voltage leakage, carbon tracking along spark plug boots, increased quenching, and erratic misfires under load that trigger check engine lights and power derating.

The Engineering Solution

This comprehensive ignition service kit utilizes four heavy-duty coil-on-plug assemblies built with high-conductivity internal copper windings and high-dielectric insulated resin housings to prevent voltage bleed. Matched with four fine-wire iridium spark plugs, this setup lowers required firing voltage while offering exceptional thermal resistance against erosion. Direct-fit blade terminals and factory-matched electrical connectors ensure plug-and-play installation without harness modification.
