Ignition Coil and Iridium Spark Plugs for Dodge Avenger (2008-2010) 3.5L

Direct-Replacement Ignition Kit for 2008-2010 Dodge Avenger

What it Does: This complete 6-cylinder ignition service kit replaces degraded factory coil packs and worn plugs to restore secondary ignition voltage, stabilize idle, and eliminate cylinder misfires under load.

The Stock Avenger Ignition Degradation

The 3.5L SOHC V6 in the JS platform engine bay subjects the rear bank ignition coils to continuous thermal cycling and trapped engine heat. Over time, OEM epoxy insulation breaks down, causing internal dielectric breakdown, micro-arcing, and high-rpm spark blowout. Coupled with worn standard electrodes that widen the spark gap, the stock ignition system suffers from increased primary resistance, sluggish throttle response, elevated hydrocarbon emissions, and intermittent P0300-P0306 misfire codes.

The Engineering Solution

Engineered for high-duty ignition demands, these coil-on-plug units feature high-conductivity copper primary and secondary windings encased in thermal-shock-resistant potting compound to prevent dielectric breakdown. Heavy-duty silicone boots provide superior arc protection against flashover in tight plug wells. Matched with fine-wire iridium spark plugs, this kit provides a concentrated, low-voltage-demand spark kernel that improves flame front propagation, optimizes combustion efficiency, and ensures rapid cold-start ignition.
