Ignition Coil and Iridium Spark Plugs for Chevrolet Trax (2015-2020) 1.4L

Direct-Fit Ignition Coil Pack and Iridium Spark Plug Kit for 2015-2020 Chevrolet Trax (Gamma II)

What it Does: The ignition coil cassette and iridium spark plug kit replaces degraded ignition components on the 2015-2020 Chevrolet Trax to eliminate secondary ignition breakdown, eradicate cylinder misfires, and stabilize combustion under turbo boost.

The Stock Chevrolet Trax Ignition Breakdown

The 1.4L Turbo LUV engine relies on an integrated four-cylinder coil rail directly mounted across the cylinder head. Over continuous thermal cycles in a pressurized forced-induction environment, heat soak causes micro-cracking across the cassette casing and degrades the internal dielectric insulation. This allows high-voltage arc-through to ground before reaching the combustion chamber. Concurrently, factory standard copper or platinum core electrodes erode, expanding the plug gap beyond nominal limits (0.9–1.0 mm). Increased resistance causes quench, spark blowout under boost, erratic idle, reduced fuel economy, and flashes fault codes P0300 through P0304.

The Engineering Solution

This refresh kit restores secondary ignition impedance and energy transfer. The one-piece cassette features high-dielectric epoxy potting, thermal-resistant silicone boots, and an exact-match 7-pin electrical harness connector that mirrors factory pinouts. Paired with fine-wire iridium spark plugs, the assembly minimizes required firing voltage while withstanding elevated combustion pressures. The durable iridium center electrode resists spark erosion, prevents gap widening, and maintains spark stability under boost.

Frequently Asked Questions & Fitment Warnings

Does this fit the Gamma II Trax?

Yes, this is a direct fit for the 2015-2020 Chevrolet Trax equipped with the LUV 1.4L turbo engine, accommodating both manual and automatic transmissions.

Do I need to apply dielectric grease during installation?

Yes, applying a thin film of dielectric grease inside each spark plug boot seals out moisture and prevents boot bonding to the ceramic plug insulator.

The Chevrolet Reliability Standard

Designed for commuter dependability and daily utility, these matched components eliminate ignition misfire under boost and ensure consistent cold-start performance across severe operating conditions.
