Ignition Coil and Iridium Spark Plugs for Dodge Challenger (2011-2023) 3.6L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2011-2023 Dodge Challenger

What it Does: Restores peak primary and secondary ignition energy to eliminate misfires, rough idle, and hesitation across the full operating range of the 3.6L Pentastar V6.

The Stock Challenger Pentastar Ignition Vulnerabilities

Under heavy thermal cycling beneath the Challenger's lower intake manifold, factory coil packs suffer from internal epoxy degradation and boot hardening. This leads to dielectric breakdown and secondary voltage arcing to the cylinder head rather than across the spark gap. Simultaneously, aged OEM spark plugs experience center and ground electrode erosion, widening the gap and straining the coil's primary windings. This results in P0300-P0306 misfire codes, erratic idle quality, and unburned hydrocarbon accumulation that degrades catalytic efficiency.

The Engineering Solution

This full 6-cylinder service kit pairs heavy-duty coil-on-plug units with fine-wire iridium spark plugs for complete combustion stability. The coils utilize oxygen-free high-conductivity copper windings and high-dielectric silicone boots that resist heat-induced flashover. Matched with fine-wire iridium plugs that require lower firing voltage while maintaining exceptional gap stability under high cylinder pressures, this package ensures immediate flame kernel propagation, crisp throttle response, and dependable high-RPM spark delivery.
