Ignition Coil and Iridium Spark Plugs for Chevrolet Volt (2016-2019) 1.5L

High-Conductivity Ignition Coil and Iridium Spark Plug Kit for 2016-2019 Chevrolet Volt

What it Does: Direct-replacement ignition service pack engineered to restore spark energy, stabilize combustion, and prevent range-extender hesitation across all hybrid operating modes.

The Stock Volt Thermal Fatigue & Spark Degradation

The 1.5L L3A range-extender engine in the second-generation Volt undergoes rapid on/off cycling and high-load transitions from electric operation. This unique thermal profile causes premature insulation breakdown in factory secondary coil windings and accelerated electrode erosion on standard plugs. Over time, the increased secondary resistance triggers spark blowout, rough generator engagement, reduced fuel efficiency, and P0300-P0304 misfire diagnostic trouble codes.

The Engineering Solution

This comprehensive ignition kit integrates four reinforced coil-on-plug units with four laser-welded iridium spark plugs. The ignition coils are manufactured with high-purity electrolytic copper windings and potted with high-dielectric epoxy resin to resist extreme temperature fluctuations and electrical leakage. Paired with fine-wire iridium center electrodes, the system reduces required firing voltage, accelerates flame kernel development, and guarantees reliable cold-engine starts under sudden high-amperage generator demands.
