Positioned directly over the spark plugs in the Modular 4.6L V8's deep cylinder head wells, these OEM coils suffer from severe heat soak over thousands of heat cycles. This prolonged exposure degrades the internal epoxy potting and internal primary windings, eventually leading to secondary voltage leaks. Furthermore, failing coil boots allow moisture to collect, resulting in carbon tracking, high-rpm misfires, hesitation under towing loads, and a severe drop in overall combustion efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition coil and spark plug kit addresses OEM thermal shortcomings through upgraded internal materials and superior external insulation. The coils feature high-temperature conductive silicone boots and enhanced dielectric epoxy potting that resists breakdown under extreme under-hood temperatures. Upgraded primary and secondary copper windings reduce internal resistance, ensuring a hotter, more stable spark output that resists blowout under load. Paired with performance-grade spark plugs designed for optimal heat dissipation and complete fuel burn, this ignition overhaul restores factory torque delivery, optimizes fuel atomization, and completely eliminates the stuttering associated with degraded COP ignition systems.\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;\"\u003e2002-2005 Ford Explorer\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;\"\u003eModular 4.6L V8 \/ U152\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;\"\u003e239 hp \/ 282 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eReplaces DG508, 1L2Z12029AA, C1417, FD503\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2002 Ford Explorer 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e2003 Ford Explorer 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e2004 Ford Explorer 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e2005 Ford Explorer 4.6L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Ford Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle the heavy towing and hauling demands of the third-generation SUV chassis, this ignition upgrade guarantees long-lasting reliability and sustained power when pulling trailers or navigating rugged terrain.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48244715028728,"sku":"DS-EG7W9AQTC","price":129.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coils-spark-plugs-for-ford-explorer-2002-2005-4-6l-1.jpg?v=1776272482","url":"https:\/\/performancechiptuning.com\/products\/ignition-coils-spark-plugs-for-ford-explorer-2002-2005-4-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
