Constant thermal cycling and severe engine bay heat soak degrade the internal resin potting compound, leading to primary and secondary winding breakdown. Over time, brittle silicone plug boots and internal conductor fatigue cause high-voltage dielectric arcing, hesitation under load, rough idling, and persistent P0300–P0306 misfire trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement kit features a reinforced one-piece coil rail housing three dual-output wasted-spark coil modules encapsulated in high-dielectric epoxy to resist thermal degradation and structural cracking. Upgraded silicone boots and corrosion-resistant stainless-steel contact springs prevent voltage leakage under high-load conditions. Paired with six fine-wire iridium spark plugs, the assembly reduces the secondary voltage required to bridge the gap, providing consistent flame kernel development, enhanced fouling resistance, and reliable combustion stability across all RPM ranges.\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 Jeep Wrangler\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;\"\u003eAMC 242 4.0L I6 \/ TJ 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;\"\u003e190 hp \/ 235 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;\"\u003eUF296, UF-296, 56041476AA, 56041476AB, 5C1181, 5C1182, C1230, C1263, 56041019, IC399, E239\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 Jeep Wrangler TJ (4.0L Inline-6 AMC 242)\u003c\/li\u003e\n  \u003cli\u003e2004-2006 Jeep Wrangler LJ Unlimited (4.0L Inline-6 AMC 242)\u003c\/li\u003e\n  \u003cli\u003eDirect interchange for OE numbers: UF296, UF-296, 56041476AA, 56041476AB, 5C1181, 5C1182, C1230, C1263, 56041019, IC399, E239\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jeep Off-Road Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe trail vibration, sustained low-RPM crawl loads, and high under-hood temperatures, this ignition kit delivers reliable firing performance and throttle response required for off-camber operation and heavy towing demands.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50428870131960,"sku":"DS-E15YXXVJZ","price":109.95,"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-jeep-wrangler-2000-2006-4-0l-1.jpg?v=1788444809","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-jeep-wrangler-2000-2006-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
