Mounted directly atop the engine block, these coils suffer from severe heat soak. Over time, the internal epoxy insulating the copper windings degrades, leading to micro-arcing. This results in weak spark energy, rough idling, hesitation under load, and P0300-series random misfire codes. Paired with aged spark plugs that exhibit widened gaps and eroded electrodes, the factory ignition system struggles to maintain complete combustion, negatively impacting fuel economy and increasing exhaust emissions.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement ignition kit is engineered to resolve the inherent thermal management issues of the OEM GM coil packs. Manufactured under strict ISO\/TS16949 quality standards, the upgraded coils utilize high-grade dielectric epoxy and reinforced copper windings to maximize thermal resistance and prevent internal voltage leaks. The optimized primary and secondary winding ratios ensure consistent, high-voltage output across the entire RPM range. Complemented by six NGK spark plugs—renowned for their precision-engineered electrodes and superior anti-fouling characteristics—this kit guarantees a stable, concentrated spark. The result is rapid flame propagation, restored 175 horsepower performance, improved throttle response, and a smooth idle, permanently curing DIS-related misfires on your 3400 V6.\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;\"\u003e1999-2005 Pontiac Grand Am\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;\"\u003eLA1 3400 V6 \/ N-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;\"\u003e175 hp \/ 205 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, GN10123 (Multi-Reference)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1999 Pontiac Grand Am 3.4L V6\u003c\/li\u003e\n  \u003cli\u003e2000 Pontiac Grand Am 3.4L V6\u003c\/li\u003e\n  \u003cli\u003e2001 Pontiac Grand Am 3.4L V6\u003c\/li\u003e\n  \u003cli\u003e2002 Pontiac Grand Am 3.4L V6\u003c\/li\u003e\n  \u003cli\u003e2003 Pontiac Grand Am 3.4L V6\u003c\/li\u003e\n  \u003cli\u003e2004 Pontiac Grand Am 3.4L V6\u003c\/li\u003e\n  \u003cli\u003e2005 Pontiac Grand Am 3.4L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Pontiac Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for daily drivability and long-term durability, this ignition kit eliminates frustrating CELs and restores the steady, reliable power expected from the classic GM 60-degree V6 architecture.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50066461425912,"sku":"DS-EM0YAQVH2","price":109.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-pontiac-grand-am-1999-2005-3-4l-v6-1.jpg?v=1785286464","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-spark-plugs-for-pontiac-grand-am-1999-2005-3-4l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
