Ignition Coil and Iridium Spark Plugs for Hyundai Accent (2012-2020) 1.6L

Direct-Replacement Ignition Coil and Iridium Spark Plug Service Kit for 2012-2020 Hyundai Accent

What it Does: Restores complete combustion efficiency and stabilizes idle by replacing aged, high-resistance factory ignition coils and eroded spark plugs with matched direct-fit components.

The Stock Accent Coil and Plug Degradation

The 1.6L Gamma direct-injection engine operates under elevated combustion pressures and rapid thermal cycling. Over time, OEM coil housings suffer microscopic epoxy degradation and internal dielectric breakdown, resulting in secondary winding voltage leakage. Paired with standard spark plug electrode erosion that widens the gap and increases secondary voltage demand, the engine develops hesitation under load, erratic idle, reduced fuel economy, and persistent P0300–P0304 cylinder misfire codes.

The Engineering Solution

This service package pairs four heavy-duty coil-on-plug assemblies with four fine-wire iridium spark plugs. The coils feature high-conductivity electrolytic copper primary and secondary windings potted in high-grade thermoplastic resin to resist thermal breakdown and voltage leakage. The iridium spark plugs feature a laser-welded center electrode for minimal spark quenching, high arc stability, and extended service life under direct-injection demands.
