Ignition Coil and Iridium Spark Plugs for Chevrolet Cruze (2017-2018) 1.6L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2017-2018 Chevrolet Cruze

What it Does: The ignition coil and iridium spark plug kit replaces worn factory ignition components on the 2017-2018 Chevrolet Cruze to eliminate cylinder misfires, restore combustion efficiency, and stabilize idle quality.

The Stock Chevrolet Cruze Secondary Ignition Breakdown

Factory pencil coils in the D2XX chassis Cruze endure intense thermal cycling inside the compact cylinder head plug wells. Over time, engine bay heat soak degrades the internal epoxy encapsulation and copper primary windings, inducing internal resistance spikes and insulation dielectric breakdown under high cylinder pressures. Concurrently, factory standard spark plug electrodes erode, widening the spark gap. This gap enlargement increases the breakdown voltage required from tired coils, triggering high-rpm hesitation, unburned hydrocarbon emissions, P0300-P0304 DTC misfire codes, and premature catalytic converter degradation.

The Engineering Solution

This complete tune-up kit restores spark energy by matching four high-dielectric pencil ignition coils with pre-gapped, wear-resistant fine-wire iridium spark plugs. The replacement coils utilize high-grade magnetic steel cores paired with premium copper winding to deliver rapid secondary voltage rise and a consistent, high-energy spark discharge. Reinforced thermoplastic housings resist thermal fracturing and oil exposure inside the head. Paired with laser-welded iridium center electrodes that survive severe thermal stress with negligible gap erosion, this kit ensures crisp flame kernel propagation, razor-sharp throttle response, and complete fuel atomization under load.
