Over time, the OEM coil packs and carbon-core plug wires develop micro-cracks in their epoxy housing and outer insulation. This dielectric breakdown leads to voltage leaks to the engine block, resulting in a rough idle, heavy hesitation under load, poor fuel economy, and eventual P0300-series misfire codes as the spark fails to jump the gap effectively under high cylinder pressures.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition overhaul kit is engineered to restore and exceed factory electrical output. The upgraded ignition coil distributor utilizes enhanced internal copper windings and high-temperature epoxy potting to resist extreme heat soak and maintain a stable voltage output across the entire RPM range. Paired with premium silicone spark plug wires, the system ensures maximum EMI\/RFI suppression with near-zero voltage drop. Finally, the included laser-welded iridium spark plugs feature a fine-wire center electrode. Iridium's superior hardness and high melting point (over 4,000°F) provide exceptional durability, ensuring a concentrated, potent spark that improves throttle response, stabilizes the idle, and maximizes the burn of the air\/fuel mixture.\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;\"\u003e2006-2010 Chevrolet Impala\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;\"\u003eHigh Value V6 (LZ4\/LZ9) \/ 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;\"\u003e211-242 hp \/ 214-240 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\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2006-2010 Chevrolet Impala 3.5L V6\u003c\/li\u003e\n  \u003cli\u003e2006-2010 Chevrolet Impala 3.9L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Chevrolet Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to complement the robust nature of American muscle and fleet-tested commuter platforms, this ignition system upgrade guarantees reliable starting power, stable highway cruising, and consistent performance mile after mile.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50142759387384,"sku":"DS-E9RGP9BDN","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-impala-2006-2010-3-5l-3-9l-v6-1.webp?v=1786463847","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-for-chevrolet-impala-2006-2010-3-5l-3-9l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
