Ignition Coil and Iridium Spark Plugs for Chevrolet Cruze (2016-2019) 1.4L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2016-2019 Chevrolet Cruze

What it Does: Restores factory secondary ignition output and cylinder-specific dwell stability to eliminate high-boost misfires, rough idle, and unburned hydrocarbon emissions on 1.4L Turbo direct-injected engines.

The Stock Cruze LE2 Thermal and Dielectric Breakdown

The forced-induction GM Ecotec 1.4L LE2 operates under elevated cylinder pressures and continuous thermal cycling inside the compact D2XX engine bay. Over time, OEM coil pack boots suffer dielectric insulation fatigue, resulting in micro-arcing and spark discharge down the plug well wall. Simultaneously, widened spark plug gaps increase electrical resistance across the secondary circuit, overloading internal copper winding insulation and causing intermittent P0300 to P0304 misfire codes under load.

The Engineering Solution

This comprehensive service pack combines four high-output ignition coils featuring high-purity internal copper windings vacuum-encapsulated in dielectric epoxy resin with heat-resistant silicone isolator boots. Paired with fine-wire iridium center electrode spark plugs, this setup substantially lowers the required ionization voltage, optimizes flame kernel propagation in direct-injected combustion chambers, and eliminates high-RPM spark blowout.
