Situated in the compact U-Body engine bay, the original coil pack is subjected to intense, prolonged heat soak. Over thousands of heat cycles, the factory epoxy resin begins to crack, leading to internal arcing, high RPM misfires, and a noticeable drop in throttle response. Furthermore, standard factory plugs can foul prematurely, increasing electrical resistance and forcing the ignition coil to work harder, which ultimately accelerates catastrophic failure across the entire ignition circuit.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis upgraded ignition coil and spark plug package is engineered to deliver sustained, high-voltage spark energy under extreme thermal loads. The replacement coil pack utilizes high-grade copper windings and a reinforced, high-dielectric epoxy housing to prevent electrical tracking and resist heat-induced cracking. Paired with ultra-fine wire iridium spark plugs, the system requires less firing voltage while providing a concentrated, hotter spark for complete fuel atomization. Additionally, the included heavy-duty silicone spark plug wires feature EMI\/RFI suppression shielding and thick insulation to protect against parasitic voltage drops. The result is a smoother idle, restored factory fuel economy, and consistent power delivery throughout the entire rev range.\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;\"\u003e2006-2008 Chevrolet Uplander\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;\"\u003e3.9L LZ9 V6 \/ U-Body (GMT201)\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;\"\u003e240 hp \/ 240 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;\"\u003eUF434, SP432, 12568185, 12579177, 12587153, 12595088\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2006 Chevrolet Uplander 3.9L V6\u003c\/li\u003e\n    \u003cli\u003e2007 Chevrolet Uplander 3.9L V6\u003c\/li\u003e\n    \u003cli\u003e2008 Chevrolet Uplander 3.9L V6\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Chevrolet Durability Standard\u003c\/h3\u003e\n  \u003cp\u003eBuilt for the daily demands of passenger transport, a reliable ignition system ensures your Uplander maintains consistent payload capacity and dependable daily drivability without throwing frustrating check engine lights.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50142767251704,"sku":"DS-EE5PW3HV5","price":134.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-chevrolet-uplander-2006-2008-3-9l-v6-1.webp?v=1786464047","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-for-chevrolet-uplander-2006-2008-3-9l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
