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

High-Output Ignition Coil & Iridium Spark Plugs for 2011-2023 Dodge Challenger, Charger (3.6L Pentastar / LA/LC/LD)

Restores ignition efficiency and eliminates misfires for high-mileage or performance-driven 3.6L engines. This direct-replacement coil and spark plug kit delivers consistent spark energy to optimize combustion, resolving hesitation and poor fuel economy associated with degraded factory ignition components.

The Stock Pentastar Ignition Degradation

The OEM ignition coils and standard spark plugs on the 3.6L Pentastar V6 are subjected to significant thermal stress due to the engine's compact cylinder head design and high operating temperatures. Over time, the factory coil boot insulation breaks down, leading to voltage leaks, weak spark, and random cylinder misfires (commonly throwing P0300-series codes). Additionally, standard factory spark plugs experience electrode erosion after 60,000 miles, increasing the spark gap. This widened gap forces the ignition coils to work harder to jump the spark, causing premature coil failure, rough idling, hesitation under heavy throttle, and a noticeable drop in overall fuel efficiency.

The Engineering Solution

This ignition kit engineered for the LA/LC/LD chassis resolves factory weaknesses by utilizing high-output ignition coils paired with precision-gapped Iridium spark plugs. The upgraded coils feature enhanced copper windings and upgraded epoxy resin that resists thermal breakdown, ensuring consistent voltage output even under extreme heat soak conditions. The included Iridium spark plugs provide a significantly harder electrode material than standard platinum or copper, practically eliminating gap erosion over the lifespan of the plug. The fine-wire Iridium center electrode concentrates spark energy, resulting in a more complete combustion event. This directly translates to smoother idle characteristics, immediate throttle response, stabilized fuel economy, and reliable performance without the risk of high-RPM spark blowout.
