Ignition Coil and Iridium Spark Plugs for Lincoln MKT (2013-2015) 3.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2013-2015 Lincoln MKT

What it Does: Restores high-voltage secondary ignition stability, resolves boost-induced misfires under load, and optimizes cylinder burn efficiency across all six cylinders.

The Stock MKT Ignition Degradation

Under the thermal constraints and elevated combustion chamber pressures of the twin-turbocharged 3.5L EcoBoost V6, factory ignition coils experience accelerated dielectric breakdown. Thermal cycling degrades internal epoxy potting and leads to micro-arcing through the boots, causing secondary voltage leakages. Simultaneously, standard plug electrode erosion widens the gap, increasing the required firing voltage beyond what fatigued OEM coil packs can supply under boost, resulting in hesitation, rough idle, and unburned hydrocarbon accumulation.

The Engineering Solution

This comprehensive tune-up kit utilizes high-grade copper primary and secondary windings encased in void-free, high-insulation dielectric epoxy to eliminate high-voltage punch-through under high manifold pressures. Matched with fine-wire iridium center electrode spark plugs, the system reduces ignition voltage demand while concentrating spark energy. The corrosion-resistant nickel-plated shells, heat-tolerant silicone boots, and direct-fit weather-pack connectors ensure clean signal delivery, stable combustion kinetics, and rapid cold starts.
