Ignition Coil + Spark Plugs for Lincoln MKT (2016-2019) 3.5L Turbo

Direct-Fit Ignition Coil and Spark Plug Tune-Up Kit for 2016-2019 Lincoln MKT (D4)

What it Does: The direct-fit ignition kit replaces worn secondary ignition components on the 2016-2019 Lincoln MKT to eliminate boost-induced misfires and restore stable, balanced cylinder combustion.

The Stock Lincoln MKT High-Boost Ignition Breakdown

The twin-turbocharged 3.5L EcoBoost V6 generates substantial in-cylinder pressures under boost, demanding exceptionally high secondary ignition voltage. Over extended heat cycles within the transverse D4 chassis engine bay, factory coil packs suffer from dielectric potting degradation and thermal fatigue. This breakdown leads to internal arcing, cracked boots, and carbon tracking. Concurrently, factory spark plug gap erosion forces tired DG549 coils past their saturation limits, causing high-load spark blowout, hesitation during acceleration, rough idle, and unburned fuel contamination in the catalytic converters.

The Engineering Solution

This comprehensive tune-up kit restores factory primary and secondary ignition stability across both cylinder banks. The replacement coils utilize high-permeability magnetic cores, precision-wound copper wiring, and reinforced silicone dielectric boots engineered to resist dielectric punch-through under high manifold pressure. Paired with forced-induction-specified spark plugs engineered with proper thermal dissipation and electrode gaps, this matched assembly ensures crisp flame-front propagation, rapid dwell response, and reliable spark energy under wide-open throttle.

Frequently Asked Questions & Fitment Warnings

Does this fit the D4 MKT?

Yes, this is a direct fit for the 2016-2019 Lincoln MKT equipped with the 3.5L EcoBoost V6 engine. This kit does not fit naturally aspirated 3.7L V6 or 2.0L models, nor does it fit commercial Livery or Limousine chassis packages.

What are the critical torque and installation requirements?

Always install components on a cold cylinder head, torque spark plugs to factory spec, and do not overtighten coil mounting fasteners into the composite valve covers.
