Ignition Coil and Iridium Spark Plugs for Mitsubishi Galant (2004-2012) 2.4L

Direct-Replacement Ignition Coil and Iridium Spark Plugs for 2004-2012 Mitsubishi Galant

Direct-fit ignition overhaul kit restores factory spark energy to eliminate misfires, rough idling, and hesitation in the 2.4L 4G69 MIVEC engine.

The Stock Galant Ignition Weakness

Over the lifespan of the DJ-chassis Galant, the factory ignition coils and standard spark plugs are prone to severe degradation due to prolonged thermal stress and cylinder head heat soak. The OEM coil boots lose dielectric integrity, leading to voltage leaks and arc-overs that often trigger P0300-series misfire codes. Simultaneously, worn spark plug electrodes increase the necessary firing voltage, which overworks the ignition coils and causes premature primary winding failure. This compound electrical breakdown results in noticeable drivability issues, including sluggish throttle response, increased fuel consumption, and severe hesitation under load.

The Engineering Solution

This comprehensive ignition service kit resolves high-mileage spark degradation by pairing precision-wound ignition coils with premium iridium spark plugs. The upgraded coils feature high-temp epoxy resin and advanced copper windings to ensure consistent voltage output even under extreme operating temperatures. The silicone boots provide maximum dielectric strength to prevent spark flashover against the engine block. Paired with fine-wire iridium spark plugs, the system requires less firing voltage to bridge the gap, significantly reducing the thermal load on the coils. The iridium center electrode resists spark erosion, offering excellent combustion efficiency, restored low-end torque, and a stabilized idle curve for the 4G69 powerplant.
