Over time, the OEM epoxy potting compound degrades, leading to micro-cracks in the coil housing. This allows moisture intrusion and electrical arcing, which manifests as a dead miss under load, sluggish acceleration, or a flashing check engine light (P0300-series codes). Paired with worn factory plugs, the weakened spark struggles to bridge the gap, resulting in unburnt fuel washing the cylinder walls and reducing the overall lifespan of your catalytic converter.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete ignition overhaul includes three high-output replacement coils and six precision-gapped NGK spark plugs engineered specifically for the L26 engine. The upgraded coils feature superior thermal epoxy and enhanced copper wire windings, significantly increasing dielectric strength to resist heat soak and high-voltage leaks. Manufactured under strict ISO\/TS16949 certification, these coils deliver a concentrated, high-energy spark that ensures complete, efficient combustion. The included NGK spark plugs utilize an advanced electrode design that prevents carbon fouling, maximizes spark efficiency, and restores the smooth, balanced power delivery the W-body chassis requires.\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;\"\u003e2005-2009 Buick LaCrosse\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;\"\u003e3800 Series III (L26) V6 \/ GM 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;\"\u003e200 hp \/ 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;\"\u003eC849SPEC, 10467067, D555, D576, EBC1518\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2005 Buick LaCrosse 3.8L V6\u003c\/li\u003e\n  \u003cli\u003e2006 Buick LaCrosse 3.8L V6\u003c\/li\u003e\n  \u003cli\u003e2007 Buick LaCrosse 3.8L V6\u003c\/li\u003e\n  \u003cli\u003e2008 Buick LaCrosse 3.8L V6\u003c\/li\u003e\n  \u003cli\u003e2009 Buick LaCrosse 3.8L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Buick Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to match GM's stringent daily driving demands, this ignition kit ensures reliable cold starts and consistent power delivery, keeping your W-body running smoothly without triggering pesky misfire codes or check engine lights.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50066445205752,"sku":"DS-EO8GZJMAO","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-lacrosse-2005-2009-3-8l-v6-1.jpg?v=1785284981","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-spark-plugs-for-buick-lacrosse-2005-2009-3-8l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
