6 High Performance Ignition Coil for Lincoln MKT (2013-2019) 3.5L Engine

Precision-Grade Ignition Coils for 2013-2019 Lincoln MKT (3.5L EcoBoost / D4)

Direct-replacement high-output ignition coils designed to eliminate spark blowout and restore combustion efficiency in the twin-turbocharged 3.5L EcoBoost engine.

The Stock MKT EcoBoost Ignition Deficit

The 3.5L EcoBoost V6 in the Lincoln MKT operates under high cylinder pressures and significant thermal stress due to its twin-turbocharger configuration. In the D4 chassis engine bay, heat soak is a persistent issue that causes the factory coil’s dielectric insulation to degrade over time. This breakdown leads to carbon tracking and internal secondary winding failure. As the spark plug gap widens through normal wear, the OEM coils often struggle to provide the necessary voltage, resulting in intermittent misfires, 'stumbling' under load, and a noticeable loss in fuel economy. These failures are typically accelerated by the tight packaging of the engine, which limits airflow around the ignition banks.

The Engineering Solution

These performance-focused coils are engineered to exceed OEM UF646 specifications by utilizing high-dielectric epoxy and reinforced silicone magnetic steel cores. The internal secondary windings feature an increased wrap density to handle higher voltage loads without internal arcing. The outer housings are constructed from high-grade, heat-resistant polymers that maintain structural integrity despite the extreme temperatures of the EcoBoost's turbochargers. To ensure a moisture-tight seal and prevent voltage leakage, this kit includes professional-grade dielectric tune-up grease. This combination ensures a consistent, high-energy spark that can reliably jump the gap even under peak boost conditions, providing smoother idle and throttle response.
