Prolonged exposure to engine bay temperatures compromises the dielectric integrity of the OE coil epoxy and wire insulation. This insulation breakdown leads to voltage leaks, resulting in inconsistent spark delivery, cylinder misfires, hesitation under heavy load, and reduced fuel economy. Furthermore, as factory spark plugs wear, the spark gap increases. This forces the standard ignition coils to work significantly harder to bridge the gap, which accelerates their eventual failure and often triggers check engine light (CEL) circuit malfunction codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition overhaul addresses OE failure points by utilizing upgraded materials for superior thermal stability and electrical conductivity. The enhanced coil packs deliver 20% more energy than standard units, stepping up a 12-volt primary charge to a robust 26,000-volt maximum secondary output. Built with premium copper internals and high-temperature resistant silicone boots, these epoxy-filled coils resist heat soak, vibration, and corrosion. Paired with 8mm high-density spark plug wires featuring protective heat shields and premium Iridium spark plugs (41-114), this system ensures a powerful, stable spark. Iridium’s extremely high melting point guarantees a consistent spark gap over time, maximizing combustion efficiency, mitigating pre-ignition risks, and restoring peak engine power and smooth idling characteristics.\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;\"\u003e2017-2020 Cadillac Escalade \/ ESV\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;\"\u003e6.2L L86 V8 \/ GMT K2XL\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;\"\u003e420 hp \/ 460 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;\"\u003eUF742 (Coils), 41-114 (Plugs), 748UU (Wires)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2017 Cadillac Escalade 6.2L V8\u003c\/li\u003e\n  \u003cli\u003e2017 Cadillac Escalade ESV 6.2L V8\u003c\/li\u003e\n  \u003cli\u003e2018 Cadillac Escalade 6.2L V8\u003c\/li\u003e\n  \u003cli\u003e2018 Cadillac Escalade ESV 6.2L V8\u003c\/li\u003e\n  \u003cli\u003e2019 Cadillac Escalade 6.2L V8\u003c\/li\u003e\n  \u003cli\u003e2019 Cadillac Escalade ESV 6.2L V8\u003c\/li\u003e\n  \u003cli\u003e2020 Cadillac Escalade 6.2L V8\u003c\/li\u003e\n  \u003cli\u003e2020 Cadillac Escalade ESV 6.2L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Cadillac Caliber\u003c\/h3\u003e\n\u003cp\u003eRestoring ignition efficiency ensures your Escalade maintains the reliable torque output required for heavy towing and smooth highway cruising, without the nuisance of misfires or rough idle.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48477659889912,"sku":"DS-EM3VXB5GW","price":219.95,"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-cadillac-escalade-esv-2017-2020-6-2l-v8-1.jpg?v=1779379765","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-iridium-spark-plugs-wire-for-cadillac-escalade-esv-2017-2020-6-2l-v8","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
