Ignition Coil and Iridium Spark Plugs for Mitsubishi Raider (2006-2008) 4.7L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2006-2008 Mitsubishi Raider 4.7L V8

What it Does: This complete 8-cylinder ignition overhaul kit restores secondary voltage stability, resolves under-load misfires, and optimizes combustion efficiency across the entire RPM band.

The Stock Raider Ignition Breakdown

The Chrysler-derived 4.7L PowerTech V8 engine in the ND platform subjects coil-on-plug assemblies to severe thermal cycling within deep cylinder head wells. Over time, OEM epoxy insulation degrades and micro-cracking occurs along the coil boots, leading to dielectric breakdown and secondary voltage leakages. Coupled with factory copper plug erosion that widens spark gaps and increases required breakdown voltage, aging ignition components cause high-RPM spark blowout, sluggish throttle response, erratic idle, and P0300-series misfire trouble codes under heavy towing loads.

The Engineering Solution

This replacement kit features eight heavy-duty ignition coils built with high-grade internal copper windings and high-dielectric epoxy potting to withstand under-hood heat soak and prevent internal shorting. Paired with fine-wire iridium spark plugs, this setup reduces the voltage demand on the ignition primary circuit. The laser-welded iridium center electrodes resist electrical arc erosion and thermal degradation, maintaining precise spark gaps for crisp cold-start ignition, linear power delivery, and complete fuel atomization under sustained load.
