Over time, engine bay heat cycles degrade factory coil potting resin and dielectric insulation boots, causing high-voltage leakage, carbon tracking, and intermittent secondary circuit breakdown. Paired with aged copper or standard platinum plugs whose electrode gaps erode over time, the increased secondary resistance overburdens the driver circuits, triggering \u003cstrong\u003eP0300-P0306\u003c\/strong\u003e diagnostic trouble codes, hesitation under load, and reduced fuel economy.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit features three heavy-duty ignition coils engineered with high-grade copper windings and vacuum-poured epoxy encapsulation to resist internal arcing and thermal breakdown. Matched with six fine-wire iridium spark plugs, the package delivers a concentrated spark discharge requiring lower firing voltage. The iridium core provides superior erosion resistance under high chamber temperatures, maintaining precise electrode gaps across extended intervals while ensuring complete flame front propagation in the \u003cstrong\u003eSigma G6CU\u003c\/strong\u003e 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; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2004-2006 Kia Amanti\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e3.5L Sigma G6CU \/ GH\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e200 hp \/ 220 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eUF439, 06C905115A, 06C905115B, 06C905115D, 06C905115E, KIN119959TOP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2004 Kia Amanti Base Sedan 4-Door 3.5L 3497CC V6 GAS DOHC Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e2005 Kia Amanti Base Sedan 4-Door 3.5L 3497CC V6 GAS DOHC Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e2006 Kia Amanti Base Sedan 4-Door 3.5L 3497CC V6 GAS DOHC Naturally Aspirated\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the GH Amanti?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2004-2006 Kia Amanti equipped with the 3.5L \u003cstrong\u003eSigma G6CU\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy are there only three coils included for a six-cylinder engine?\u003c\/strong\u003e\u003cbr\u003e The 3.5L V6 utilizes a waste-spark ignition configuration where three dual-tower coils each fire one direct cylinder and one companion cylinder via high-tension plug leads.\u003c\/p\u003e\n\n\u003ch3\u003eThe Kia Sedan Precision Standard\u003c\/h3\u003e\n\u003cp\u003ePreserve factory cruising refinement and smooth power delivery by refreshing the secondary ignition system with components engineered to withstand high underhood operating temperatures without check-engine lights or voltage drop.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50604897861880,"sku":"DS-EXZ3GA82T","price":85.95,"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-kia-amanti-2004-2006-3-5l-1.jpg?v=1790089254","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-kia-amanti-2004-2006-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
