OEM ignition coils experience internal winding resistance changes due to constant heat cycling near the cylinder heads. This thermal stress breaks down the epoxy potting compound, leading to micro-cracking and voltage leaks. Additionally, aging factory spark plugs suffer from electrode erosion, widening the spark gap and increasing voltage demand on stressed coils. This culminates in chronic misfires, reduced fuel economy, and potential unburnt fuel damaging the catalytic converter over time.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis ignition service kit rectifies OEM shortcomings by utilizing ISO\/TS16949 certified manufacturing. The included ignition coils feature upgraded copper windings with optimized turn ratios to ensure consistent, high-energy voltage output. High-grade epoxy resin is vacuum-injected to eliminate air pockets, drastically improving thermal conductivity and heat resistance. Paired with NGK spark plugs featuring precision-engineered electrodes and superior ceramic insulators to prevent flashover, this system ensures an efficient combustion burn. The resulting spark stability enhances throttle response, smooths W-Body chassis vibrations at idle, and restores fuel efficiency without premature coil saturation.\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;\"\u003e1994-2005 Buick Century\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;\"\u003e3.1L V6 (L82 \/ LG8) \/ A-Body \u0026amp; W-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;\"\u003e160-175 hp \/ 185-195 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;\"\u003eC849SPEC, 2-5192, EBC1518, GN10123, D555\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1994-2005 Buick Century 3.1L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Buick Durability Standard\u003c\/h3\u003e\n\u003cp\u003eMaintain the smooth, vibration-free ride that the Century was designed for.
