Over extended heat cycles within the transverse \u003cstrong\u003eD4\u003c\/strong\u003e chassis engine bay, factory coil packs suffer from dielectric potting degradation and thermal fatigue. This breakdown leads to internal arcing, cracked boots, and carbon tracking. Concurrently, factory spark plug gap erosion forces tired \u003cstrong\u003eDG549\u003c\/strong\u003e coils past their saturation limits, causing high-load spark blowout, hesitation during acceleration, rough idle, and unburned fuel contamination in the catalytic converters.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit restores factory primary and secondary ignition stability across both cylinder banks. The replacement coils utilize high-permeability magnetic cores, precision-wound copper wiring, and reinforced silicone dielectric boots engineered to resist dielectric punch-through under high manifold pressure. Paired with forced-induction-specified spark plugs engineered with proper thermal dissipation and electrode gaps, this matched assembly ensures crisp flame-front propagation, rapid dwell response, and reliable spark energy under wide-open throttle.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e6x Direct-Replacement Coil-on-Plug Ignition Coils\u003c\/li\u003e\n  \u003cli\u003e6x Turbo-Specified Pre-Gapped 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;\"\u003e2016-2019 Lincoln MKT\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;\"\u003e3.5L EcoBoost V6 \/ D4\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;\"\u003e365 hp \/ 350 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;\"\u003eDG549, SP534, UF646, IC749, 2505-484814, BL3Z-12029-C, E1146, 673-6300, 5C1871, SP537, SP580, SP528, CYFS-12-Y3\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\u003e2016 Lincoln MKT EcoBoost 3.5L Turbo (3.5L V6 GAS DOHC Turbocharged)\u003c\/li\u003e\n  \u003cli\u003e2017-2019 Lincoln MKT 3.5L Turbo (Base, Elite, Reserve)\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 D4 MKT?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2016-2019 Lincoln MKT equipped with the \u003cstrong\u003e3.5L EcoBoost V6\u003c\/strong\u003e engine. \u003cstrong\u003eThis kit does not fit naturally aspirated 3.7L V6 or 2.0L models, nor does it fit commercial Livery or Limousine chassis packages.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eWhat are the critical torque and installation requirements?\u003c\/h4\u003e\n\u003cp\u003eAlways install components on a cold cylinder head, torque spark plugs to factory spec, and do not overtighten coil mounting fasteners into the composite valve covers.\u003c\/p\u003e\n\n\u003ch3\u003eThe Lincoln Caliber\u003c\/h3\u003e\n\u003cp\u003eMaintain the executive ride quality, silent cruising dynamics, and confident towing capacity of your twin-turbo crossover with ignition components matched to forced-induction tolerances.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67579070611704,"sku":"DS-EB5DBRZX2","price":175.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-lincoln-mkt-2016-2019-3-5l-turbo-1.jpg?v=1791250424","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-spark-plugs-for-lincoln-mkt-2016-2019-3-5l-turbo","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
