Over time, the factory coil packs suffer from dielectric breakdown and micro-cracking in the epoxy resin casing. Degraded primary and secondary copper windings increase internal resistance, causing weak spark delivery, delayed flame front propagation, rough idling, elevated fuel consumption, and high-RPM misfire trouble codes under heavy acceleration.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 6-cylinder refresh kit pairs high-output coil-on-plug assemblies with erosion-resistant fine-wire iridium spark plugs for balanced combustion. Built with premium thermal-resistant internal copper windings, durable silicone boots, and precision blade terminals, each coil ensures fast charging and stable discharge. The matched iridium plugs resist gap widening and thermal shock, delivering reliable arc generation, crisp throttle response, and smooth power delivery throughout the rev range.\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;\"\u003e2016-2019 Cadillac ATS\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;\"\u003e3.6L LGX V6 \/ GM 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;\"\u003e335 hp \/ 285 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;\"\u003eUF830, UF-830, 12666339\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2016 Cadillac ATS 3.6L V6 (Sedan \/ Coupe)\u003c\/li\u003e\n  \u003cli\u003e2017 Cadillac ATS 3.6L V6 (Sedan \/ Coupe)\u003c\/li\u003e\n  \u003cli\u003e2018 Cadillac ATS 3.6L V6 (Sedan \/ Coupe)\u003c\/li\u003e\n  \u003cli\u003e2019 Cadillac ATS 3.6L V6 (Coupe)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Cadillac Precision Standard\u003c\/h3\u003e\n\u003cp\u003eManufactured to precise direct-injection electrical tolerances, this complete ignition kit ensures proper dwell times without triggering CEL warnings, preserving the smooth refinement and responsive driving dynamics expected from the Alpha platform.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50454221390072,"sku":"DS-E2NGHK0NE","price":129.95,"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-2016-2019-3-6l-1.jpg?v=1788726683","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-cadillac-ats-2016-2019-3-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
