Ignition Coil & Iridium Spark Plugs for Dodge Magnum (2006-2008) 5.7L 6.1L V8

High-Output Ignition Coil & Iridium Spark Plugs for 2006-2008 Dodge Magnum (5.7L/6.1L Hemi)

Direct replacement ignition system upgrade designed to restore misfire conditions, stabilize idle, and maximize combustion efficiency for high-displacement Hemi V8 engines.

The Stock LX Platform Ignition Degradation

5.7L and 6.1L Hemi engines utilize a dual-spark plug per cylinder configuration that puts massive thermal and electrical strain on the factory ignition coils. Over time, OEM coil packs experience severe heat soak due to their placement inside the recessed valve covers. This trapped radiant heat degrades the internal epoxy, leading to micro-cracks in the coil housing, increased electrical resistance, and voltage leaks. Simultaneously, standard factory plugs experience rapid electrode erosion, expanding the gap beyond tolerances. The result is a weak spark, intermittent misfires under heavy load, reduced fuel economy, and sluggish throttle response.

The High-Voltage Engineering Solution

This ignition overhaul addresses OEM thermal failures by utilizing upgraded materials and advanced circuitry. The included 8 ignition coils feature high-temperature epoxy and reinforced dielectric boots, significantly improving thermal shock resistance and preventing high-voltage arcing under load. Premium copper internal windings reduce primary resistance, delivering a faster, more consistent voltage spike. Paired with 16 performance iridium spark plugs, this kit ensures a highly stable spark kernel. Iridium’s high melting point allows for a micro-fine center electrode, minimizing the voltage required to jump the gap while maintaining precise tolerances. This translates to complete fuel combustion, restored factory torque, and reliable cold starts.
