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.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2019-2021 Lincoln Nautilus\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2.7L EcoBoost Nano V6 \/ CD4 (U540)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e335 hp \/ 380 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eKT4Z12029A, UF-827, UF827, KIN135766TOP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2019 Lincoln Nautilus Reserve 2.7L V6 Twin Turbo\u003c\/li\u003e\n  \u003cli\u003e2019 Lincoln Nautilus Black Label 2.7L V6 Twin Turbo\u003c\/li\u003e\n  \u003cli\u003e2020 Lincoln Nautilus Reserve 2.7L V6 Twin Turbo\u003c\/li\u003e\n  \u003cli\u003e2020 Lincoln Nautilus Black Label 2.7L V6 Twin Turbo\u003c\/li\u003e\n  \u003cli\u003e2021 Lincoln Nautilus Reserve 2.7L V6 Twin Turbo\u003c\/li\u003e\n  \u003cli\u003e2021 Lincoln Nautilus Black Label 2.7L V6 Twin Turbo\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the CD4 Nautilus?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2019-2021 Lincoln Nautilus equipped with the 2.7L EcoBoost Nano engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre the spark plugs pre-gapped for turbo boost pressures?\u003c\/strong\u003e\u003cbr\u003e Yes, the iridium plugs are preset to factory specifications, though verifying gap with a feeler gauge prior to installation is recommended.\u003c\/p\u003e\n\n\u003ch3\u003eThe Lincoln Refinement Standard\u003c\/h3\u003e\n\u003cp\u003eMaintaining the whisper-quiet cabin and smooth power delivery of your Lincoln luxury crossover requires factory-grade ignition tolerances without check-engine lights, ensuring seamless highway cruising and sustained torque under load.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50594154447096,"sku":"DS-EJOOW8YBX","price":124.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-and-iridium-spark-plugs-for-lincoln-nautilus-2019-2021-2-7l-1.jpg?v=1790057494","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-lincoln-nautilus-2019-2021-2-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
