Ignition Coil and Iridium Spark Plugs for Chevrolet Spark (2012-2015) 1.2L

Direct-Replacement Ignition Tune-Up Kit for 2012-2015 Chevrolet Spark

What it Does: Restores factory secondary ignition voltage and combustion efficiency by replacing worn coil-on-plug assemblies and fouled spark plugs to eliminate misfires and hesitation.

The Stock Spark Ignition Degradation

The compact engine bay of the M300 platform subjects the factory ignition components to severe heat cycling. Over time, OEM coil pack epoxy resin breaks down, allowing dielectric leakage and internal copper winding degradation. This results in weak spark energy, premature electrode erosion on standard plugs, increased secondary resistance, and common diagnostic trouble codes such as P0300 through P0304 under load.

The Engineering Solution

This comprehensive service kit pairs four direct-fit coil-on-plug units with fine-wire iridium spark plugs. The ignition coils feature high-conductivity copper windings insulated with premium epoxy potting and reinforced silicone boots to resist thermal breakdown and prevent flashover. Paired with corrosion-resistant iridium electrodes that require lower striking voltage, this setup stabilizes flame kernel growth, improves throttle response, and smooths engine idle.
