Ignition Coil and Iridium Spark Plugs for Mitsubishi Outlander (2004-2006) 2.4L

Direct-Replacement Ignition Coil and Iridium Spark Plugs for 2004-2006 Mitsubishi Outlander

What it Does: This complete ignition service kit replaces worn factory coils and fouled plugs to restore proper spark energy, eliminating misfires and stabilizing idle quality.

The Stock CU5W Ignition Weakness

Over time and mileage, the factory ignition coils on the 2.4L 4G69 engine suffer from internal resistance degradation and dielectric breakdown. The constant heat cycling within the engine bay degrades the internal epoxy potting compound, leading to voltage leaks and weak spark delivery. Simultaneously, standard or worn spark plugs experience electrode erosion, which increases the spark gap. This creates excessive resistance that forces the ignition coils to overwork, accelerating coil failure. Symptoms of this ignition deterioration include rough idling under load, acceleration hesitation, reduced fuel economy, and P0300-series misfire codes triggering the check engine light.

The Engineering Solution

This comprehensive ignition kit directly addresses these failures by pairing high-output ignition coils with premium iridium spark plugs. The upgraded coils feature heavy-duty copper wire windings and high-dielectric epoxy to maximize voltage output and resist thermal breakdown, ensuring a consistent, powerful spark under high-load conditions. The included spark plugs utilize a highly durable, fine-wire iridium center electrode. Iridium's extreme melting point prevents gap erosion, allowing for a highly concentrated spark that improves overall combustion efficiency. This combination ensures a complete fuel burn, resolving hesitation, smoothing out the idle, and restoring factory throttle response without requiring modifications to the original engine wiring harness.
