OEM-Grade Ignition Coil and Iridium Spark Plug Kit for 2007-2010 Lincoln MKX

Direct-Fit Ignition Service Kit: Complete 6-cylinder tune-up solution engineered to eliminate secondary ignition breakdown, intermittent misfires, and rough idle under heavy load.

The Stock MKX Coil Degradation and Spark Wear

The 3.5L Duratec V6 runs high thermal cycles beneath tightly packaged intake plenum runners. Over time, OEM coil-on-plug epoxy casings suffer dielectric breakdown and micro-fracturing from engine bay heat soak. This leads to internal resistance drift, high-voltage leakage, and unburned fuel entering the exhaust. Factory nickel-tipped spark plugs also erode at the ground strap, widening the spark gap and overworking the primary coil windings until severe engine hesitation or CEL misfire codes (P0300–P0306) occur.

The Engineering Solution

This comprehensive kit restores factory combustion efficiency with 6 high-dielectric coil-on-plug assemblies and 6 fine-wire iridium spark plugs. Each ignition coil is built with high-grade internal copper windings and thermoplastic housings to resist thermal fatigue and prevent voltage arcing. The paired iridium plugs feature laser-welded fine-wire center electrodes that require lower striking voltage while resisting carbon fouling, ensuring crisp throttle response, steady idle stability, and optimized flame front propagation across the entire RPM band.
