Ignition Coil and Iridium Spark Plugs for Lincoln MKZ (2013-2020) 2.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2013-2020 Lincoln MKZ

Primary Function: Restores high-voltage ignition energy and stable combustion across all four cylinders in turbocharged direct-injected applications, eliminating spark blowout and rough idle.

The Stock MKZ Ignition Degradation

The forced-induction 2.0L EcoBoost engine subjects factory coil-on-plug units to severe thermal cycling and high cylinder pressures. Over time, OEM primary and secondary epoxy insulation micro-cracks, leading to internal dielectric breakdown, secondary voltage leakage, and coil boot arcing. Compounding this, standard factory spark plugs experience accelerated center electrode gap erosion under high direct-injection combustion temperatures. This degradation manifests as hesitation under boost, rough idle, increased fuel consumption, and intermittent P0300-P0304 misfire trouble codes.

The Engineering Solution

This comprehensive ignition service kit pairs four upgraded coil-on-plug assemblies with four precision-gapped fine-wire iridium spark plugs. The ignition coils feature premium insulated copper windings sealed within high-dielectric epoxy housing to resist thermal saturation and maximize output voltage under elevated boost pressures. Oil- and heat-resistant silicone boots provide robust arc-over protection, while direct-fit blade terminals ensure low-resistance electrical connectivity. The iridium spark plugs maintain a stable spark gap longer than nickel or platinum, reducing required firing voltage and optimizing flame kernel propagation.
