Ignition Coil and Iridium Spark Plugs for Chrysler 300 (2005) 2.7L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for Chrysler 300

Precision Ignition Overhaul: Delivers complete primary-to-secondary ignition restoration for the 2.7L V6 platform, eliminating misfire codes, erratic idle, and secondary voltage loss under load.

The Stock Chrysler 300 Ignition Vulnerability

The factory coil-on-plug assemblies on the 2.7L EER V6 are subjected to continuous thermal cycling in the LX chassis engine bay. Over extended service cycles, excessive underhood heat degrades the internal epoxy potting and leads to micro-arcing and dielectric breakdown. Simultaneously, standard factory spark plugs experience electrode erosion that widens the gap, increasing the secondary voltage required to bridge the spark and accelerating coil burnout.

The Engineering Solution

This comprehensive ignition pack features six heavy-duty coil-on-plug units wound with high-purity copper wiring and insulated with premium thermal epoxy to prevent dielectric punch-through. Matched with fine-wire iridium spark plugs, the kit reduces the required firing voltage, accelerates flame front propagation, and provides consistent combustion under all load states. Direct-fit OEM-style blade connectors ensure positive retention without wiring harness modifications.
