Over time, relentless engine bay heat cycling causes the epoxy potting within the OEM coil packs to micro-crack, allowing moisture intrusion and critical voltage leaks. This typically manifests as a P0300 random misfire code, hesitation under acceleration, poor fuel economy, and a noticeably rough idle. Paired with worn or fouled spark plugs, the resulting weak spark fails to fully ignite the air-fuel mixture, accelerating carbon buildup on the intake valves and oxygen sensors.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete ignition overhaul kit combines three precision-wound ignition coils with six highly conductive NGK spark plugs to correct these inherent electrical flaws. The upgraded coils utilize high-dielectric epoxy and heavy-gauge copper wire windings that resist thermal shock and voltage bleed, ensuring maximum energy transfer directly to the spark plugs. Manufactured to strict ISO\/TS16949 quality standards, the improved magnetic core design guarantees a rapid recharge time and sustained spark duration even under heavy engine loads. The included NGK spark plugs feature advanced metallurgical properties that resist gap erosion, providing a precise and stable arc that maximizes combustion efficiency and restores factory throttle response.\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;\"\u003e2002-2005 Buick Rendezvous\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 3.4L LA1 V6 \/ GMT257\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;\"\u003e185 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;\"\u003eC849 \/ 10467067 \/ D545 \/ 5192\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2002 Buick Rendezvous 3.4L V6\u003c\/li\u003e\n  \u003cli\u003e2003 Buick Rendezvous 3.4L V6\u003c\/li\u003e\n  \u003cli\u003e2004 Buick Rendezvous 3.4L V6\u003c\/li\u003e\n  \u003cli\u003e2005 Buick Rendezvous 3.4L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Buick Durability Standard\u003c\/h3\u003e\n\u003cp\u003eDesigned for the daily driving demands and passenger payloads of the GMT257 crossover chassis, this complete ignition package ensures steadfast electrical reliability, smoother hauling operations, and consistent power delivery in all weather conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50066450088184,"sku":"DS-EYS8BGTJK","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-buick-rendezvous-2002-2005-3-4l-v6-1.jpg?v=1785285201","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-spark-plugs-for-buick-rendezvous-2002-2005-3-4l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
