Over time, internal winding insulation deteriorates, leading to dielectric punch-through, secondary voltage leakages, carbon tracking, and intermittent misfire codes (P0300–P0306). Paired with standard worn spark plugs, high firing resistance places excessive load on the PCM driver circuits.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis kit features reinforced coil assemblies manufactured with high-conductivity internal copper windings and durable dielectric housings that resist thermal fatigue and breakdown under sustained cylinder head temperatures. Fitted with factory-matched direct-fit blade connectors, the coils deliver low-loss primary current transfer. The included fine-wire iridium spark plugs lower the required ionization voltage, deliver a concentrated spark kernel for complete flame-front propagation, and offer superior resistance to spark erosion compared to standard nickel alloys.\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;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2005-2008 Mercury Mariner\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e3.0L Duratec 30 V6 \/ Ford CD2 Platform\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e200 hp \/ 193 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number \/ Interchange\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eDG500, DG513, FD495, FD502, UF406, E261, C1387, C1458, 5C1617, 5C1449\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2005 Mercury Mariner 3.0L V6 (Convenience, Premier)\u003c\/li\u003e\n  \u003cli\u003e2006 Mercury Mariner 3.0L V6 (Convenience, Premier)\u003c\/li\u003e\n  \u003cli\u003e2007 Mercury Mariner 3.0L V6 (Convenience, Premier)\u003c\/li\u003e\n  \u003cli\u003e2008 Mercury Mariner 3.0L V6 (Base, Premier)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Mercury Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to endure the daily demands of commuter and all-weather crossover service, this comprehensive ignition kit ensures immediate cold-weather starts, steady fuel efficiency, and factory-level reliability under all driving conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50448499605752,"sku":"DS-ERVTFTIG4","price":71.95,"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-mercury-mariner-2005-2008-3-0l-1.jpg?v=1788647686","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-mercury-mariner-2005-2008-3-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
