Ignition Coil and Iridium Spark Plugs for Lincoln Nautilus (2019-2021) 2.7L

High-Dielectric Ignition Coil and Iridium Spark Plug Kit for 2019-2021 Lincoln Nautilus

What it Does: The ignition coil and iridium spark plug kit restores factory spark energy and precise combustion timing on the 2019-2021 Lincoln Nautilus 2.7L to eliminate misfires under boost and restore peak fuel economy.

The Stock Lincoln Nautilus Secondary Ignition Breakdown

The twin-turbocharged 2.7L EcoBoost Nano engine operates under high cylinder pressures and severe thermal cycling. Over time, factory coil pack boots harden, micro-crack, and succumb to dielectric breakdown, allowing high-voltage flashover to ground before reaching the combustion chamber. Concurrently, standard electrode gaps erode from spark blowout under boost, creating secondary ignition resistance that strains the PCM drivers and triggers P0300 through P0306 DTC misfire codes under load.

The Engineering Solution

This comprehensive tune-up kit replaces all six factory ignition units with heavy-duty pencil coils and matched fine-wire iridium spark plugs. The direct-fit coil-on-plug modules feature high-grade copper windings and heat-resistant epoxy encapsulation to prevent internal shorting across high-ambient-heat cylinder banks. Paired with laser-welded iridium electrode spark plugs, this assembly maintains a stable, consistent arc gap resistant to spark erosion and fouling, ensuring crisp throttle response and clean combustion under full boost.
