Ignition Coil and Iridium Spark Plugs for Mercury Milan (2006-2009) 2.3L

Direct-Fit Ignition Coil & Iridium Spark Plug Kit for 2006-2009 Mercury Milan

What it Does: Restores factory secondary ignition performance by replacing degraded coil packs and worn spark plugs to eliminate misfires, rough idle, and unburned hydrocarbon emissions.

The Stock Milan Ignition Breakdown

The 2.3L Duratec engine operates under high thermal cycles within a compact cylinder head design. Over time, OEM coil-on-plug (COP) assemblies suffer from thermal degradation of the internal epoxy resin and dielectric breakdown in the primary/secondary copper windings. Concurrently, factory standard plugs experience electrode erosion, increasing the gap distance. This elevated resistance overburdens the aging coil windings, resulting in intermittent spark scatter, erratic idle under load, decreased fuel economy, and P0300-P0304 diagnostic trouble codes.

The Engineering Solution

This complete tune-up kit features four direct-replacement ignition coils engineered with high-conductivity copper windings, reinforced thermoplastic housings, and corrosion-resistant blade terminals for maximum dielectric strength. Paired with fine-wire iridium-tipped spark plugs, this setup ensures lower required firing voltage, exceptional thermal resilience, and a concentrated spark kernel. The result is rapid flame kernel propagation, complete combustion chamber burn, immediate throttle response, and reliable cold-start ignition.
