Ignition Coil and Iridium Spark Plugs for Dodge Avenger (2008-2010) 2.7L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2008-2010 Dodge Avenger

What it Does: Replaces degrading factory ignition coils and eroded spark plugs to eliminate misfires, stabilize idle, and restore peak combustion efficiency in 2.7L V6 powertrains.

The Stock Avenger Thermal Breakdown

Under the compact transverse layout of the JS platform, the Chrysler 2.7L EER DOHC V6 generates significant under-hood thermal load. Over extended thermal cycling, factory coil boots crack and internal primary/secondary winding insulation breaks down, causing internal arcing and intermittent misfire codes (P0300–P0306). Concurrently, worn factory plugs experience electrode erosion that widens the spark gap, placing severe electrical strain on the ignition drivers and causing hesitation under load.

The Engineering Solution

This comprehensive tune-up kit replaces all six ignition stations with reinforced coil-on-plug assemblies and premium fine-wire iridium spark plugs. The replacement coils feature high-conductivity copper windings potted in high-dielectric epoxy resin to prevent voltage leaks under severe heat soak. Paired with laser-welded iridium electrode spark plugs, the kit reduces the required firing voltage, accelerates flame kernel development, and guarantees reliable, high-energy spark delivery across the entire RPM band.
