Ignition Coil and Iridium Spark Plugs for Mitsubishi Eclipse (2006-2012) 3.8L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2006-2012 Mitsubishi Eclipse 3.8L

What it Does: Replaces degraded factory secondary ignition components to eliminate high-load misfires, stabilize idle RPM, and restore complete combustion across all six cylinders.

The Stock Eclipse Ignition Thermal Breakdown

The transverse mounting of the 3.8L 6G75 V6 engine causes severe heat trapping along the firewall-facing rear cylinder bank. Over extended thermal cycles, the factory epoxy encapsulation in OEM coil packs degrades, causing microscopic insulation fractures, secondary voltage leakage, and internal copper winding resistance drift. Paired with worn nickel-core plugs, this increased resistance overburdens the driver circuits, manifesting as hesitations under load, rough idle, and unburned fuel entering the exhaust tract.

The Engineering Solution

This comprehensive ignition kit features high-grade electrolytic copper primary and secondary windings insulated by vacuum-poured dielectric epoxy resin to resist high-temperature breakdown. Thermoplastic boot housings prevent arcing at high dwell times. Matched with fine-wire iridium-tipped spark plugs with high melting points and superior electrical conductivity, the kit lowers ignition system voltage demand, prevents plug quenching, and delivers stable arc discharge throughout the 6,500 RPM powerband.
