Ignition Coil & Iridium Spark Plugs for Dodge Challenger Charger (2006-2022) 5.7L 6.1L 6.2L 6.4L V8

High-Output Ignition Coil & Iridium Spark Plugs for 2006-2022 Dodge Challenger (Gen III Hemi / LC, LA)

Replaces degrading OEM ignition components to restore optimal spark energy, reduce misfires, and ensure complete combustion across the entire RPM range.

The Stock Gen III Hemi Ignition Shortcomings

The factory twin-spark ignition system on the Gen III Hemi V8 is highly dependent on consistent coil voltage and plug gap integrity. Over time, frequent thermal cycling within the engine bay degrades the internal epoxy and primary windings of the OEM coils, leading to voltage leakage and weak spark generation. Concurrently, standard spark plugs suffer from rapid electrode erosion under high-compression and high-load conditions. This degradation manifests as high-RPM misfires, inconsistent idle quality, delayed throttle response, and incomplete fuel atomization, ultimately robbing the engine of mechanical efficiency and contributing to heat soak vulnerabilities.

The Engineering Solution

Upgrading to this comprehensive performance ignition package resolves these thermal and electrical vulnerabilities. The ignition coils are engineered with upgraded primary and secondary copper windings, insulated by high-dielectric epoxy that resists high-temperature degradation and prevents high-voltage breakdown. This ensures a prolonged spark duration and maximum voltage output per cycle. Paired with 16 performance iridium-tipped spark plugs, the system guarantees an exceptionally stable and concentrated spark. The ultra-fine iridium center electrodes maintain their precise gap tolerances even under the extreme cylinder pressures of the 5.7L, 6.1L, 6.2L, and 6.4L engines, optimizing the flame front for increased horsepower, torque stability, and a cleaner, more efficient fuel burn.
