Ignition Coil + Iridium Spark Plugs for Mitsubishi Eclipse (2000-2003) 2.4L

Direct-Fit Ignition Coil & Iridium Spark Plug Service Kit for 2000-2003 Mitsubishi Eclipse

What it Does: The ignition coil and iridium spark plug kit restores primary secondary ignition energy on the 2000-2003 Mitsubishi Eclipse to eliminate cylinder misfires, rough idle, and unburned hydrocarbon wash.

The Stock Mitsubishi Eclipse Waste-Spark Breakdown

The factory ignition layout on the third-generation D52A platform relies on a 2-coil waste-spark system mounted directly above the valve cover. Constant thermal cycling from the cylinder head degrades the internal copper winding insulation and epoxy potting within factory coils like MD362907, leading to high-voltage dielectric breakdown under load. Coupled with standard nickel-copper plugs that erode rapidly, the widening spark gap increases the required breakdown voltage. This causes intermittent spark blow-out, catalytic converter overheating from unburned fuel, and engine codes P0300 through P0304 under hard acceleration.

The Engineering Solution

This comprehensive service package replaces aged factory components with two high-dielectric coil packs and four fine-wire iridium spark plugs engineered specifically for the 4G64 engine architecture. The coils feature reinforced secondary winding spools and high-grade magnetic steel cores to deliver consistent kilovolt output across the entire rev range. Paired with laser-welded iridium electrode spark plugs featuring low quenching characteristics and high thermal conductivity, this kit lowers secondary ignition circuit resistance, stabilizes flame front propagation, and provides superior resistance to carbon fouling compared to conventional copper cores.
