Ignition Coil + Iridium Spark Plugs for Mitsubishi Lancer (2002-2007) 2.0L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2002-2007 Mitsubishi Lancer

What it Does: The ignition coil and iridium spark plug kit restores secondary voltage stability and spark energy on the 2002-2007 Mitsubishi Lancer to eliminate misfires, stabilize idle, and restore fuel efficiency.

The Stock Mitsubishi Lancer Ignition Breakdown

Under repeated thermal cycling in the compact CS6A engine bay, factory ignition coils on the 4G94 engine suffer internal insulation breakdown. Over decades of heat soak, the factory epoxy resin micro-fractures, prompting secondary dielectric punch-through, spark arc-over, and fluctuating resistance. Simultaneously, standard plugs experience electrode erosion, increasing the gap distance. This gap expansion forces the aging coils to generate higher breakdown voltages, accelerating coil fatigue and leading to misfire codes (P0300-P0304) and hesitation under engine load.

The Engineering Solution

This balanced ignition maintenance package addresses ignition load dynamics on the 2.0L SOHC platform. The kit includes two direct-fit coil-on-plug modules wound with premium copper magnet wire encapsulated in high-grade thermoset epoxy to isolate against high-voltage leakage and internal shorting. Paired with four fine-wire iridium spark plugs featuring laser-welded 0.6mm tips, the kit minimizes required ionization energy, ensures rapid flame-kernel growth, and delivers superior thermal dissipation across prolonged heat cycles.

Frequently Asked Questions

Does this fit the CS6A Lancer?
Yes, this is a direct fit for the 2002-2007 Mitsubishi Lancer equipped with the 4G94 engine.

Why are there only two coils for a 4-cylinder engine?
The 2.0L 4G94 utilizes a waste-spark setup where two coil packs mount over cylinders 2 and 4, connecting to cylinders 1 and 3 via secondary high-tension leads.
