Ignition Coil and Iridium Spark Plugs for Lincoln MKZ (2013-2016) 3.7L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2013-2016 Lincoln MKZ

Direct-fit replacement ignition tune-up kit: Restores factory ignition energy, eliminates secondary voltage leakage, and prevents misfires under load for the 3.7L V6 powertrain.

The Stock MKZ Ignition Degradation and Misfire Issues

Under-hood thermal cycling in the transverse engine bay causes dielectric breakdown of factory coil boots and internal insulation over time. High operating temperatures degrade primary and secondary windings, resulting in high internal resistance, voltage drop-off, and carbon tracking. Worn factory plugs experience widened electrode gaps, leading to intermittent spark blowout, unburned fuel bypass, rough idle, and sluggish throttle response.

The Engineering Solution

This service kit features heavy-duty coil-on-plug assemblies built with high-conductivity copper windings insulated with high-grade epoxy to prevent high-voltage arcing. Matched with fine-wire iridium spark plugs, this system provides superior thermal stability and lower required firing voltage compared to standard copper or platinum. Reinforced silicone boots and precision blade terminals ensure positive electrical contact and resist heat-soak deterioration for consistent combustion chamber flame propagation.
