Ignition Coil and Iridium Spark Plugs for Dodge Intrepid (1998-2004) 2.7L

Direct-Replacement Ignition Coil and Iridium Spark Plug Service Kit for 1998-2004 Dodge Intrepid

Complete Secondary Ignition Refresh: Restores factory secondary ignition performance, stabilizes idle fluctuations, and resolves misfire DTCs across all 6 cylinders on the 2.7L DOHC platform.

The Stock Intrepid Coil Degradation

The deep-well coil-on-plug architecture in the LH 2.7L DOHC engine exposes factory ignition coils to extreme thermal cycling and oil vapor degradation. Over time, internal primary and secondary copper winding insulation degrades, leading to dielectric breakdown, inter-turn shorting, and weakened secondary voltage output under high cylinder pressure. Paired with eroded conventional nickel spark plugs, high secondary resistance induces engine stumbling, incomplete fuel combustion, and P0300-P0306 misfire codes.

The Engineering Solution

This matched overhaul kit includes six high-dielectric coil-on-plug assemblies paired with ultra-fine-wire iridium spark plugs. The coils feature high-conductivity copper windings and reinforced thermoplastic housings to resist thermal breakdown and voltage leakage. The fine-wire iridium center electrodes significantly lower ignition voltage demand while providing exceptional resistance to electrical erosion, ensuring crisp flame front propagation, reliable cold starting, and consistent combustion efficiency.
