Over time, original epoxy insulation suffers internal dielectric breakdown and copper primary windings develop micro-shorts. Concurrently, standard copper or platinum plugs experience electrode erosion, widening the spark gap. This combined degradation causes secondary voltage leakage, cylinder misfires under load, rough idle, increased emissions, and premature catalytic converter fouling.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement kit pairs six reinforced coil packs with six precision fine-wire iridium spark plugs. The coil assemblies feature high-grade magnetic copper windings insulated with premium dielectric epoxy to resist high-voltage tracking and thermal breakdown under severe duty. Combined with laser-welded iridium electrode spark plugs that require lower firing voltage and resist spark erosion, this kit delivers consistent spark delivery, sharp throttle response, stable idle, and complete fuel burn.\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;\"\u003e2004-2008 Dodge Durango\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;\"\u003e3.7L PowerTech V6 (EKG) \/ HB 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;\"\u003e210 hp \/ 235 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Numbers \/ Interchange\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUF270, 56028138AB, 56028138AD, 56028138AE, 56028138AF, 56028138, 52-2034, 5C1114\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2004-2008 Dodge Durango (3.7L V6 SOHC)\u003c\/li\u003e\n  \u003cli\u003eDirect interchange with OE numbers: UF270, 56028138AB, 56028138AD, 56028138AE, 56028138AF, 56028138, 52-2034, 5C1114\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Dodge Truck Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle sustained thermal loads and the demands of daily towing or hauling, this complete ignition refresh maintains steady combustion pressures to eliminate misfire-related power loss under load.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50448855105784,"sku":"DS-EJEWRTYY4","price":81.95,"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-dodge-durango-2004-2008-3-7l-1.jpg?v=1788661816","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-dodge-durango-2004-2008-3-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
