Concurrently, factory carbon-core plug wires endure thermal fatigue from nearby exhaust manifolds, leading to elevated conductor resistance, boot carbon tracking, and spark scatter. When paired with high-mileage electrode erosion on stock plugs, coil dwell saturation degrades, triggering rough idle harmonics, power loss on steep climbs, and P0300 random misfire trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete ignition kit utilizes high-output round D585\/UF262 coil architectures encapsulated in high-grade dielectric epoxy potting to resist thermal cycling and eliminate secondary winding breakdown. Low-resistance 8mm silicone-jacketed plug wires feature stranded copper cores and stainless-steel terminal heat shields to repel radiant manifold heat. Combined with laser-welded fine-wire iridium spark plugs, this package lowers required discharge voltage, sharpens flame kernel development, and guarantees reliable cylinder combustion under heavy towing loads.\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;\"\u003e2003-2007 Hummer H2\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;\"\u003e6.0L Vortec LQ4 V8 \/ GMT820\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;\"\u003e316–325 hp \/ 360–365 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;\"\u003eUF262, D585, 41-962, 19299585, 12192195\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2003-2007 Hummer H2:\u003c\/strong\u003e Base, Adventure, and Luxury trims equipped with the 6.0L Vortec V8 (Round UF262\/D585 coil body only; not compatible with square UF271 coils)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOE Coil Interchange:\u003c\/strong\u003e UF262, D585, C1251, 10457730, 12563293, 12573190, 8104577300, 8125731900, GN10119, 5C1082, E254, E254P, 52-1647, IC413, 6737101, 19005218\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Interchange:\u003c\/strong\u003e 12192195, 9748GG, 748GG, 748UU, 12622553, 88862397, 12656210, XS10388, 12192192, 7873\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlug Interchange:\u003c\/strong\u003e 19299585, 41-962\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Hummer Heavy-Duty Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered specifically to withstand high-duty cycles, extreme underhood thermal saturation, and continuous low-speed crawling, this ignition kit provides the durable combustion reliability required for heavy vehicle recovery, steep ascents, and maximum towing performance.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50498314862840,"sku":"DS-EBS1E6GVU","price":185.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-wire-for-hummer-h2-2003-2007-6-0l-1.jpg?v=1789266239","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-iridium-spark-plugs-wire-for-hummer-h2-2003-2007-6-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
