Ignition Coil and Iridium Spark Plugs for Mitsubishi Eclipse (2006-2012) 2.4L

Direct-Replacement Ignition Kit for 2006-2012 Mitsubishi Eclipse

Restores proper combustion and eliminates misfire codes by replacing degraded factory ignition components with fresh coils and iridium-tipped plugs.

The Stock Eclipse 4G69 Ignition Weakness

Over thousands of heat cycles, the factory ignition coils on the 2.4L 4G69 engine suffer from internal winding breakdown and boot degradation. Engine bay temperatures cause the epoxy potting within the OEM coils to micro-crack, leading to voltage leaks and weak spark delivery. Simultaneously, worn spark plugs develop widened gap tolerances, increasing resistance. This combination results in rough idling, sluggish throttle response, decreased fuel economy, and P0300-series misfire codes. If left unchecked, this weak combustion sends unburned fuel into the exhaust, accelerating catalytic converter wear.

The Engineering Solution

This ignition service kit resolves voltage drop-off by pairing high-output ignition coils with matched iridium spark plugs. The replacement coils (UF-532 equivalent) feature upgraded copper windings and high-dielectric epoxy housings, ensuring consistent secondary voltage transfer under high thermal loads. The included iridium-tipped spark plugs (3656 spec) require significantly less voltage to jump the gap compared to traditional plugs. The ultra-fine center electrode concentrates electrical energy, resulting in a more complete flame kernel. This restores OEM fuel efficiency, stabilizes the idle, and ensures sharp acceleration across the entire RPM band.
