Ignition Coil and Iridium Spark Plugs for Chevrolet Equinox (2018-2020) 2.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2018-2020 Chevrolet Equinox

What it Does: Restores factory ignition energy, stabilizes combustion cycles, and eliminates cylinder misfires across the turbocharged 2.0L direct-injected powertrain.

The Stock Equinox Ignition Breakdown

The turbocharged 2.0L LTG Ecotec operates under high cylinder pressures and severe thermal cycling. Over extended service intervals, OEM epoxy encapsulation degrades, allowing dielectric breakdown in the secondary windings. Coupled with electrode erosion on aging spark plugs, this causes increased secondary resistance, coil thermal saturation, unmetered spark blowout under boost, rough idle, and P0300-P0304 diagnostic trouble codes.

The Engineering Solution

This complete 4-cylinder ignition kit pairs high-grade copper primary and secondary winding coil-on-plug packs with fine-wire iridium spark plugs. The coils feature reinforced thermoplastic housings and high-dielectric silicone boots to isolate spark discharge and resist heat soak. Premium iridium center electrodes provide a concentrated spark kernel at lower operational voltages, ensuring instant ignition under peak boost, reducing direct-injection carbon load, and restoring throttle response.
