Ignition Coil and Iridium Spark Plugs for Chrysler 300 (2006-2010) 3.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2006-2010 Chrysler 300

Complete Ignition Overhaul: Replaces degraded factory coil packs and fouled spark plugs to eliminate secondary ignition breakdown, cylinder misfires, and unstable idle under heavy engine load.

The Stock 300 Thermal Breakdown and Misfire Vulnerability

Factory coil-on-plug modules on the 3.5L V6 endure intense thermal cycling and underhood heat soak within the LX chassis engine bay. Over high mileage cycles, OEM internal epoxy insulation micro-fractures and internal copper windings degrade, triggering dielectric leakage, spark scatter, hesitation, and unburned fuel delivery that rapidly fouls downstream catalytic converters.

The Engineering Solution

This comprehensive ignition service package features heavy-duty coil packs manufactured with high-grade electrolytic copper primary and secondary windings encased in high-dielectric epoxy resin for maximum arc suppression and thermal resilience. Paired with fine-wire iridium spark plugs engineered with elevated melting points and reduced firing voltage demands, this system restores precise spark kernel propagation, crisp throttle response, and complete combustion across all engine loads.
