Years of under-hood heat cycling cause the epoxy potting compound within the OEM coils to dry out, crack, and lose their dielectric strength. This internal breakdown allows high-voltage spark energy to arc internally or short to ground, resulting in a weak spark at the plug. For the driver, this manifests as rough idling, stalling at stoplights, cylinder misfires under load, and a blinking Check Engine Light. Coupled with worn-out, gap-widened factory spark plugs, the aging ignition system drastically reduces fuel economy, increases emissions, and diminishes overall engine responsiveness.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis ignition overhaul kit provides an engineered fix by pairing ISO\/TS16949 certified replacement coil packs with premium NGK spark plugs. The upgraded ignition coils feature high-temperature epoxy potting and advanced copper wire windings to optimize the primary-to-secondary winding ratio, maximizing voltage output while resisting thermal breakdown. This robust construction effectively shields the internal electronics from the severe heat soak typical in the H-Body and G-Body engine bays. Paired with NGK spark plugs—renowned for their precise gap retention, superior copper core heat dissipation, and anti-corrosion plating—this kit guarantees a complete, high-energy burn in the combustion chamber. The result is a smooth idle, restored low-end torque, and reliable long-term operation under heavy electrical loads.\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;\"\u003e1988-2005 Buick LeSabre\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;\"\u003eGM 3800 V6 (L27\/L36) \/ H-Body \u0026amp; G-Body\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;\"\u003e165-205 hp \/ 210-230 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;\"\u003eC849 \/ D555 \/ 10467067\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1988-2005 Buick LeSabre 3.8L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Buick Caliber\u003c\/h3\u003e\n\u003cp\u003eDesigned for absolute reliability.
