Ignition Coil & Spark Plugs for Lincoln MKT MKX (2016-2018) 3.7L V6

Direct-Replacement Ignition Coil & Spark Plugs for 2016-2018 Lincoln MKT, MKX

Restores optimal combustion and eliminates misfires by replacing degraded OEM ignition components. This complete kit provides six direct-fit ignition coils and six premium platinum spark plugs designed specifically for the 3.7L Cyclone V6 engine.

The Stock MKT, MKX Ignition Weakness

Over time, the factory ignition system on the 3.7L Cyclone engine is highly susceptible to thermal degradation and voltage leaks. Prolonged exposure to extreme engine bay temperatures causes the epoxy resin inside the OEM ignition coils to crack, leading to internal short circuits and a weakened spark. Paired with standard spark plug electrode wear, this thermal breakdown results in rough idling, delayed throttle response, inconsistent fuel economy, and cylinder misfire codes (P0300-P0306) that compromise overall engine efficiency and drivability.

The Engineering Solution

This comprehensive ignition kit engineered for the D4 and CD4 chassis directly targets these common electrical failures. The upgraded ignition coils are wound with high-conductivity copper wiring and housed in a heat-resistant, high-dielectric polymer casing to prevent voltage leakage and withstand extreme heat cycles. Paired with platinum-grade spark plugs, the system ensures a highly focused, consistent spark across all RPM ranges. The platinum center electrode resists erosion significantly better than traditional copper, maximizing service life while restoring factory power delivery, stabilizing idle characteristics, and maintaining optimal fuel atomization for the Cyclone V6.
