Ignition Coil and Iridium Spark Plugs for Chevrolet Equinox (2018-2022) 1.5L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2018-2022 Chevrolet Equinox

What it Does: Restores factory ignition energy, stabilizes idle, and eliminates cylinder misfires on the turbocharged 1.5L Ecotec engine by replacing degraded ignition coils and worn factory spark plugs with high-grade components.

The Stock Equinox Ignition Degradation

The direct-injected, turbocharged 1.5L LYX engine operates under high cylinder pressures and elevated thermal cycles within the compact D2XX engine bay. Over time, OEM ignition coils suffer from dielectric breakdown in the lower insulation boots and thermal stress across internal primary and secondary copper windings. Concurrently, standard spark plug electrodes erode from constant spark discharge, widening the plug gap. This combined wear leads to elevated resistance, weak spark generation, hesitation under boost, rough cold idling, and intermittent P0300-P0304 misfire trouble codes.

The Engineering Solution

This complete 4-cylinder service kit pairs high-output direct-fit ignition coils with premium fine-wire iridium spark plugs. The coils feature high-conductivity internal copper windings encased in high-dielectric epoxy resin to prevent internal arc-over and thermal degradation. The paired iridium spark plugs utilize laser-welded fine-tip center electrodes designed for lower voltage demand, exceptional thermal conductivity, and long service life. This setup ensures consistent spark delivery across the entire RPM band, promoting complete fuel combustion, smooth throttle response, and dependable cold-start reliability.
