Over time, OEM coil housings experience micro-fractures in the potting epoxy, allowing high-voltage secondary arc leakage to the cylinder head rather than the plug gap. Simultaneously, aged factory plugs suffer from electrode erosion, widening the gap and over-saturating the primary driver circuit, resulting in P0300-P0308 trouble codes and rough acceleration under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive kit restores full ignition performance by pairing heavy-duty coil-on-plug assemblies with fine-wire iridium spark plugs. The ignition coils feature high-purity oxygen-free copper internal windings and reinforced dielectric casings that resist heat soak and thermal degradation. The included fine-wire iridium plugs significantly reduce arc quenching, lower the required firing voltage, and ensure rapid, complete flame kernel expansion across the combustion chamber.\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;\"\u003e2006-2011 Buick Lucerne\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;\"\u003e4.6L Northstar V8 (LD8 \/ L37) \/ GM G Platform\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;\"\u003e275-292 hp \/ 288-295 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;\"\u003eUF564, 12597745, 12602862, 12670154, D596A, C1556\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2006–2011 Buick Lucerne CXS (4.6L V8 Northstar LD8)\u003c\/li\u003e\n  \u003cli\u003e2008–2011 Buick Lucerne Super (4.6L V8 Northstar L37)\u003c\/li\u003e\n  \u003cli\u003e2008–2011 Buick Lucerne CXL (4.6L V8 Northstar LD8)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Buick Smooth-Idle Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet OE electrical impedance specifications, this ignition package preserves the refined NVH characteristics of the GM G-body platform, ensuring consistent cold-start ignition and seamless power delivery without setting spurious misfire DTCs.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50447752724728,"sku":"DS-EZ1QDYFOC","price":169.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-and-iridium-spark-plugs-for-buick-lucerne-2006-2011-4-6l-1.jpg?v=1788623173","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-buick-lucerne-2006-2011-4-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
