Over high mileage, the factory epoxy insulation on stock coils develops micro-fissures, inducing dielectric breakdown and high-RPM spark scatter. Simultaneously, OEM spark plug wires deteriorate near hot exhaust manifolds, increasing resistance and degrading secondary voltage delivery to worn plugs.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit features high-output round D585-style ignition coils built with dense epoxy potting and integrated aluminum heat sinks for superior thermal dissipation. Matched with 8mm red silicone-jacketed wires featuring low-resistance stranded copper cores and stainless heat-shielded boots, it ensures maximum voltage transfer while shielding against EMI. Laser-welded iridium spark plugs offer superior erosion resistance and maintain precise gap tolerances across extreme operating temperatures.\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;\"\u003e2000-2006 GMC Yukon \/ Yukon XL\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;\"\u003eVortec Gen III V8 (LR4, LM7, L59, LQ4) \/ GMT800\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;\"\u003e275-335 hp \/ 290-380 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\u003e2000-2006 GMC Yukon 4.8L V8 (Round D585 Coils)\u003c\/li\u003e\n  \u003cli\u003e2000-2006 GMC Yukon 5.3L V8 (Round D585 Coils)\u003c\/li\u003e\n  \u003cli\u003e2000-2006 GMC Yukon 6.0L V8 (Round D585 Coils)\u003c\/li\u003e\n  \u003cli\u003e2000-2006 GMC Yukon XL 1500 5.3L V8 (Round D585 Coils)\u003c\/li\u003e\n  \u003cli\u003e2000-2006 GMC Yukon XL 2500 6.0L V8 (Round D585 Coils)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe GMC Towing Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle the continuous duty cycles of heavy towing and payload hauling, this system delivers dependable spark energy to keep your Vortec V8 running strong across severe operating conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50498310799608,"sku":"DS-ENR28N16G","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-gmc-yukon-yukon-xl-1500-2500-2000-2006-4-8l-5-3l-6-0l-1.jpg?v=1789266116","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-wire-for-gmc-yukon-yukon-xl-1500-2500-2000-2006-4-8l-5-3l-6-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
