Ignition Coil and Iridium Spark Plugs for Lincoln MKX (2016-2018) 2.7L

Direct-Replacement Ignition Coil and Iridium Spark Plug Service Kit for 2016-2018 Lincoln MKX

Primary Function: Restores factory secondary ignition voltage and combustion efficiency across all cylinders on twin-turbocharged 2.7L EcoBoost engines.

The Stock MKX Ignition Degradation Under Boost

The 2.7L EcoBoost engine subjects ignition coils and spark plugs to intense cylinder pressures and severe thermal cycling. Over time, factory coil insulation degrades from localized heat soak, leading to internal dielectric breakdown, micro-arcing, and intermittent misfires under heavy load. Simultaneously, standard plug electrodes erode from high-boost spark blowout conditions, widening the gap and straining the secondary winding circuit, causing rough idle and hesitation.

The Engineering Solution

This complete ignition overhaul kit features six coil-on-plug assemblies engineered with high-conductivity internal copper windings and high-dielectric epoxy potting to resist thermal degradation and voltage leak. Paired with fine-wire iridium spark plugs, the setup ensures concentrated spark energy, stable flame-front propagation, lower firing voltage demand, and consistent spark delivery across the full RPM band without premature gap erosion.
