Over time, extreme underhood thermal cycling causes internal dielectric breakdown in the factory epoxy windings. This results in secondary voltage leakage, carbon tracking down the plug insulator, and intermittent misfires under load that trigger diagnostic trouble codes and degraded fuel economy.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis service kit resolves voltage drop by pairing high-output coil-on-plug units with fine-wire iridium spark plugs matching OEM number \u003cstrong\u003eUF855\u003c\/strong\u003e. The coils utilize vacuum-impregnated epoxy encapsulation to resist heat soak and internal shorting, seated inside high-temp silicone boots that isolate secondary current. The accompanying iridium plugs feature a laser-welded fine-wire electrode, lowering required ignition voltage and providing superior anti-fouling resistance across all four cylinders.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e4 Black Coil-on-Plug Ignition Coils\u003c\/li\u003e\n  \u003cli\u003e4 Fine-Wire Iridium Spark Plugs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100 style=\" border-collapse: collapse border: solid font-size: min-width:\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;\"\u003e2019-2023 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;\"\u003e\n\u003cstrong\u003e2.0L EcoBoost I4\u003c\/strong\u003e \/ \u003cstrong\u003eCD4\u003c\/strong\u003e\n\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;\"\u003e250 hp \/ 280 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;\"\u003e\u003cstrong\u003eUF855\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2019-2023 Lincoln Nautilus Standard 2.0L I4\u003c\/li\u003e\n  \u003cli\u003e2019-2023 Lincoln Nautilus Select 2.0L I4\u003c\/li\u003e\n  \u003cli\u003e2019-2023 Lincoln Nautilus Reserve 2.0L I4\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the CD4 Nautilus?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2019-2023 Lincoln Nautilus equipped with the \u003cstrong\u003e2.0L EcoBoost\u003c\/strong\u003e engine. \u003cstrong\u003eDoes not fit 2.7L EcoBoost V6 models.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need dielectric grease during installation?\u003c\/h4\u003e\n\u003cp\u003eApplying a thin film of dielectric grease inside the silicone boots prevents boot adhesion, blocks moisture intrusion, and deters high-voltage corona arcing.\u003c\/p\u003e\n\n\u003ch3\u003eThe Lincoln Refinement Standard\u003c\/h3\u003e\n\u003cp\u003eLincoln crossover platforms demand clean, balanced ignition performance to maintain cabin quietness and smooth power delivery.
