Ignition Coil and Iridium Spark Plugs for Dodge Avenger (2008-2010) 2.0L

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

Primary Function: Restores factory ignition energy and precise secondary spark timing to eliminate misfires, stabilize idle quality, and restore peak combustion efficiency across the rev range.

The Stock Avenger Coil Breakdown and Spark Degradation

Factory coil packs on the 2.0L World Engine endure aggressive heat cycling within the compact JS chassis engine compartment. Over time, original coil insulation and internal epoxy potting degrade, generating micro-fractures that induce high-voltage dielectric breakdown and secondary winding resistance drift. Combined with standard spark plug electrode erosion, this creates excessive electrical load on the primary ignition circuit, manifesting as P0300–P0304 misfire codes, hesitations under load, and unburnt fuel waste.

The Engineering Solution

This complete direct-fit ignition kit combines reinforced coil-on-plug assemblies with ultra-durable fine-wire iridium spark plugs. The ignition coils feature high-conductivity internal copper windings and high-dielectric epoxy potting to withstand high thermal loads without insulation puncture. The matched iridium plugs require lower ionization voltage to fire, ensuring immediate flame kernel formation, reduced electrical stress on the coils, and dependable operation through extreme combustion temperatures.
