Ignition Coil & Iridium Spark Plugs for Pontiac G6 (2006-2010) 2.4L I4

High-Energy Ignition Coils & Iridium Spark Plugs for 2006-2010 Pontiac G6 (LE5 Ecotec / GM Epsilon)

Direct Replacement Ignition Kit: Restores factory spark output and corrects misfire conditions to ensure complete combustion and a steady idle in the 2.4L Ecotec engine.

The Stock G6 Ignition Degradation

The OEM ignition coils and spark plugs on the LE5 2.4L Ecotec engine are notorious for thermal degradation over extended mileage. Subjected to continuous heat cycling under the hood of the GM Epsilon chassis, the internal epoxy potting of the factory coils breaks down, leading to micro-arcing and voltage leaks. This typically manifests as intermittent misfires (P0300 codes), rough idling, sluggish throttle response, and unburnt fuel entering the exhaust stream. Furthermore, standard factory spark plugs experience rapid electrode wear, widening the spark gap and forcing the deteriorating coils to work even harder to bridge the gap, which accelerates complete ignition failure.

The Engineering Solution

This comprehensive replacement kit pairs four high-output ignition coils with precisely gapped iridium spark plugs to completely overhaul the G6 ignition system. The upgraded coils feature premium copper windings and a high-dielectric epoxy housing to resist thermal breakdown and eliminate voltage tracking. By delivering a more concentrated spark energy, the coils optimize fuel burn efficiency, thereby restoring lost horsepower and low-end torque. The included iridium spark plugs utilize a fine-wire center electrode that requires less voltage to fire while maintaining a highly stable spark over an extended lifespan. Together, this combination ensures reliable cold starts, smooths out rough idles, and maximizes combustion efficiency across the entire RPM range.
