Ignition Coil and Iridium Spark Plugs for Mazda CX-3 (2016-2019) 2.0L

High-Dielectric Ignition Coil and Iridium Spark Plug Service Kit for 2016-2019 Mazda CX-3

What it Does: Restores high-voltage secondary ignition output and precise combustion timing for the 2.0L Skyactiv-G engine to eliminate misfires, rough idle, and spark blowout under load.

The Stock CX-3 High-Compression Ignition Breakdown

The high 13.0:1 static compression ratio of the Skyactiv-G direct-injection platform demands high secondary breakdown voltage across the spark gap. Over extended heat-cycling cycles, factory epoxy and copper primary windings within the pencil coils suffer thermal degradation, resulting in internal insulation breakdown, micro-arcing, and intermittent misfire codes (P0300-P0304). Simultaneously, worn center electrodes elevate primary resistance, straining the driver circuits and degrading catalytic converter efficiency.

The Engineering Solution

This complete tune-up kit features heavy-duty coil-on-plug units wound with high-grade copper wire and sealed in high-dielectric epoxy to prevent internal flashover under severe thermal stress. Paired with fine-wire DILKAR7G11GS iridium spark plugs, the laser-welded iridium tip reduces required firing voltage, providing superior anti-fouling characteristics and sustained flame-kernel propagation throughout high-RPM direct-injection load cycles.
