As the OEM epoxy potting cracks from continuous under-hood heat soak, moisture penetrates the secondary windings. This increases internal electrical resistance, leading to weak spark propagation, high-rpm breakup, rough idle conditions, and cylinder misfires under load. Additionally, fouled or worn factory copper spark plugs exacerbate the issue by requiring higher voltage to bridge the spark gap, forcing the aging coils to overwork and eventually burn out the internal primary windings entirely.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis comprehensive tune-up kit replaces the restrictive and failure-prone OEM setup with three high-dielectric resin-potted ignition coils and six precision-gapped NGK spark plugs. Manufactured under strict ISO\/TS16949 quality control standards, the upgraded coils feature heavy-duty copper wiring and advanced magnetic steel cores to maximize voltage output and ensure a much faster rise time. The included NGK spark plugs provide a highly conductive center electrode and superior ceramic insulators to prevent electrical flashover. By renewing both the voltage generation and delivery components simultaneously, this kit restores factory fuel economy, sharpens throttle response, and guarantees a consistent, high-energy spark across the entire RPM 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;\"\u003e1990 Buick Electra\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;\"\u003eBuick 3800 V6 (LN3) \/ GM C-Body (FWD)\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;\"\u003e165 hp \/ 210 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;\"\u003eD555, 10467067, GN10123, 2-5192\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e1990 Buick Electra 3.8L V6\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Buick Comfort Standard\u003c\/h3\u003e\n  \u003cp\u003eEnsuring your classic C-body maintains its smooth, uninterrupted power delivery is essential for the refined driving experience expected from a premium American luxury sedan.
