Ignition Coil and Iridium Spark Plugs for Mitsubishi Raider (2006-2008) 3.7L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2006-2008 Mitsubishi Raider

Primary Function: Direct-replacement complete ignition service kit engineered to eliminate secondary ignition breakdown, cylinder misfires, and rough idle under load in the 3.7L V6 platform.

The Stock Raider Ignition Degradation

Factory coil packs on the PowerTech 3.7L suffer from thermal cycling fatigue, leading to micro-cracking in the epoxy insulation and resistance drift across the internal copper windings. Paired with standard plug electrode erosion that widens the gap over time, the ignition system requires higher secondary voltage to arc, resulting in intermittent P0300–P0306 misfire codes, incomplete combustion, decreased fuel efficiency, and sluggish throttle response under payload.

The Engineering Solution

This kit restores factory ignition parameters using six heavy-duty ignition coils paired with six fine-wire iridium spark plugs. The coils feature high-grade electrolytic copper windings and high-dielectric potting compound to resist heat-induced insulation breakdown, terminated with direct-fit OEM blade connectors. The matched iridium plugs provide superior thermal dissipation, exceptional wear resistance against spark erosion, and consistent arc projection under high cylinder pressures.
