Over time, high ambient cylinder-head heat degrades internal potting epoxy, inducing micro-arcing and intermittent secondary voltage dropouts. When paired with standard spark plug electrode erosion, the resulting increased resistance causes unburned fuel mixtures, sluggish throttle response, rough idle conditions, and diagnostic trouble codes such as P0300 through P0304.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis ignition service pack pairs high-conductivity internal copper windings with corrosion-resistant blade terminals for maximum energy transfer to the combustion chamber. Thermally stabilized silicone boots prevent flashover under heavy engine load, while the matched fine-wire iridium spark plugs provide exceptional wear resistance and a lower required firing voltage. The result is rapid flame kernel propagation, complete fuel burn, and consistent spark delivery across the entire RPM band.\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 Buick Envision\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 I4 \/ GM D2XX\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;\"\u003e197 hp \/ 192 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, 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\u003e2017 Buick Envision 2.5L L4 (Base, Preferred, Essence)\u003c\/li\u003e\n  \u003cli\u003e2018 Buick Envision 2.5L L4 (Base, Preferred, Essence)\u003c\/li\u003e\n  \u003cli\u003e2019 Buick Envision 2.5L L4 (Base, Preferred, Essence)\u003c\/li\u003e\n  \u003cli\u003e2020 Buick Envision 2.5L L4 (Base, Preferred, Essence)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Buick Refinement Standard\u003c\/h3\u003e\n\u003cp\u003ePreserve the smooth, vibration-free cabin environment engineered for Buick luxury crossovers.
