Over time, factory coil-on-plug boots and epoxy insulation degrade under sustained underhood thermal cycling. This dielectric breakdown leads to secondary voltage leakage, micro-arcing, carbon tracking, and high-load misfires (DTC P0300-P0304). Paired with eroded factory plug gaps, weak spark energy degrades fuel atomization and creates rough cold starts.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete tune-up kit replaces all four ignition packs and spark plugs simultaneously. Coils are manufactured with high-grade copper primary and secondary windings encased in thermally stable potting epoxy, ensuring consistent high-voltage output without internal dielectric breakdown. Paired with fine-wire iridium spark plugs offering superior thermal conductivity, lower arc voltage requirements, and high anti-fouling resistance, this kit ensures crisp throttle response and clean combustion.\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;\"\u003e2013-2017 Cadillac ATS (2.5L L4 Gas)\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;\"\u003e2.5L LCV Ecotec \/ Alpha 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;\"\u003e202 hp \/ 191 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;\"\u003eUF680, UF-680, 12654078, 12627120, 12652400, C869, C1827, 5C1884\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2013 Cadillac ATS Base \/ Luxury 2.5L L4 - Gas\u003c\/li\u003e\n  \u003cli\u003e2014 Cadillac ATS Base \/ Luxury 2.5L L4 - Gas\u003c\/li\u003e\n  \u003cli\u003e2015 Cadillac ATS Base \/ Luxury 2.5L L4 - Gas\u003c\/li\u003e\n  \u003cli\u003e2016 Cadillac ATS Base \/ Luxury 2.5L L4 - Gas\u003c\/li\u003e\n  \u003cli\u003e2017 Cadillac ATS Base \/ Luxury 2.5L L4 - Gas\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Cadillac Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact OEM resistance and dwell parameters, these ignition components integrate seamlessly with the factory ECM to maintain zero check engine lights and factory-smooth idle quality.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50448299163896,"sku":"DS-E7WYE7PWT","price":100.95,"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-cadillac-ats-2013-2017-2-5l-1.jpg?v=1788639233","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-cadillac-ats-2013-2017-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
