Ignition Coil and Iridium Spark Plugs for Dodge Challenger (2009-2010) 3.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2009-2010 Dodge Challenger

Complete Ignition Refresh: This 6-cylinder direct-replacement ignition service kit eliminates secondary voltage leakage, rough idle, and acceleration hesitation by renewing the complete spark delivery system on the 3.5L V6 Challenger.

The Stock Challenger SOHC V6 Ignition Breakdown

Factory coil packs on the LC chassis 3.5L High Output V6 suffer from prolonged thermal cycling inside the cylinder head wells. Over time, internal epoxy insulation breaks down and primary copper windings fatigue, causing spark energy to dissipate before reaching the combustion chamber. When combined with worn, gap-widened spark plugs, the increased electrical resistance strains the ignition system, resulting in unburnt fuel, sluggish throttle response, reduced fuel efficiency, and P0300-P0306 misfire codes under load.

The Engineering Solution

This comprehensive overhaul kit features six coil-on-plug units built with premium internal copper windings and high-dielectric epoxy potting to resist thermal degradation and prevent dielectric punch-through. Factory-spec blade terminals and direct-fit connectors ensure zero-resistance signal transmission. Paired with six fine-wire iridium spark plugs, the system requires lower firing voltage while providing high melting-point durability, producing a stable flame kernel and restoring factory engine efficiency.
