Ignition Coil and Iridium Spark Plugs for Lincoln MKZ (2017-2020) 3.0L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2017-2020 Lincoln MKZ

What it Does: Restores factory secondary ignition output, eliminating high-boost spark blowout and rough idle across all six cylinders on twin-turbocharged models.

The Stock MKZ Ignition Breakdown

Under elevated cylinder pressures generated by the twin-turbocharged 3.0L Nano V6, factory ignition coils endure severe thermal cycling and dielectric breakdown within the engine valley. Over time, heat-soak degrades the internal epoxy potting and insulation surrounding the copper windings, inducing secondary voltage leakage and resistance drift. Combined with gradual spark plug electrode erosion, these degrading components cause hesitation under load, erratic idle, and ignition misfires under peak boost.

The Engineering Solution

This comprehensive kit features high-grade copper primary and secondary windings encased in reinforced thermal housing to resist dielectric puncture and heat fatigue. Precision blade terminals and direct-fit electrical connectors maintain low contact resistance. Paired with fine-wire iridium-tipped spark plugs engineered for superior thermal dissipation and high-arc stability, this matched package ensures precise flame propagation, fast cold-start ignition, and consistent combustion efficiency.
