Ignition Coil and Iridium Spark Plugs for Kia Rio (2012-2020) 1.6L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2012-2020 Kia Rio

What it Does: Restores complete primary and secondary ignition efficiency across all four cylinders to eliminate misfires, rough idle, and unburned fuel waste.

The Stock Rio Ignition Coil Breakdown

The Gamma 1.6L engine positions its coil-on-plug boots deep inside the cylinder head wells, subjecting the factory ignition coils to continuous thermal cycling and engine bay heat soak. Over time, OEM primary and secondary copper windings experience insulation breakdown, while standard spark plug ground electrodes suffer from high-voltage erosion. This degradation causes internal dielectric arcing, intermittent spark dropouts under acceleration, fouled plugs, and frequent P0300-P0304 cylinder misfire fault codes.

The Engineering Solution

This comprehensive service kit replaces fatigued ignition hardware with four heavy-duty coil-on-plug assemblies and four fine-wire iridium spark plugs. Engineered with high-grade copper windings and premium dielectric epoxy potting, these coils resist high-temperature breakdown and provide consistent spark energy across the entire RPM range. Paired with high-melting-point iridium center electrodes, this package ensures rapid flame kernel expansion, crisp throttle response, clean cold starts, and reliable combustion stability under load.
