Because each coil fires on both compression and exhaust strokes, their thermal duty cycle is double that of sequential ignition systems. Over time, extreme underhood thermal cycling causes factory epoxy potting to crack, resulting in internal insulation breakdown, secondary resistance spikes, and severe carbon tracking. Combined with worn plugs that require higher ionization voltage, this breakdown manifests as P0300-series misfire codes, hesitations under load, and unburned fuel entering the catalytic converters.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive service kit resolves voltage drop and misfire issues by pairing three high-output replacement coil packs with six fine-wire iridium spark plugs. The coils are engineered with high-dielectric PBT housings and vacuum-impregnated epoxy encapsulation to block moisture and eliminate micro-arcing under high thermal loads. High-permeability silicon steel magnetic cores match OEM primary\/secondary winding parameters, offering a direct replacement for interchange numbers \u003cstrong\u003eUF432\u003c\/strong\u003e, \u003cstrong\u003eCUF267\u003c\/strong\u003e, and \u003cstrong\u003e5C1193\u003c\/strong\u003e. The included iridium-tipped spark plugs feature laser-welded fine-wire center electrodes that demand lower firing voltages, ensuring stable arc projection, cleaner flame-front propagation, and maximum erosion resistance under waste-spark demands.\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;\"\u003e2002-2005 Kia Sedona\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 \/ GQ\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;\"\u003e195 hp \/ 218 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;\"\u003eUF432, CUF267, C748, 5C1193, 1788315, GN10536, KIN119961TOP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2002 Kia Sedona EX Minivan 3.5L V6 (Sigma G6CU)\u003c\/li\u003e\n  \u003cli\u003e2002 Kia Sedona LX Minivan 3.5L V6 (Sigma G6CU)\u003c\/li\u003e\n  \u003cli\u003e2003 Kia Sedona EX Minivan 3.5L V6 (Sigma G6CU)\u003c\/li\u003e\n  \u003cli\u003e2003 Kia Sedona LX Minivan 3.5L V6 (Sigma G6CU)\u003c\/li\u003e\n  \u003cli\u003e2004 Kia Sedona EX Minivan 3.5L V6 (Sigma G6CU)\u003c\/li\u003e\n  \u003cli\u003e2004 Kia Sedona LX Minivan 3.5L V6 (Sigma G6CU)\u003c\/li\u003e\n  \u003cli\u003e2005 Kia Sedona EX Minivan 3.5L V6 (Sigma G6CU)\u003c\/li\u003e\n  \u003cli\u003e2005 Kia Sedona LX Minivan 3.5L V6 (Sigma G6CU)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the GQ Sedona?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2002-2005 Kia Sedona equipped with the \u003cstrong\u003eSigma G6CU\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does this 6-cylinder kit only include three ignition coils?\u003c\/strong\u003e\u003cbr\u003e The 3.5L V6 utilizes a waste-spark setup where three dual-tower coil packs each drive two companion spark plugs simultaneously.\u003c\/p\u003e\n\n\u003ch3\u003eThe Kia Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eDesigned to handle the high thermal cycles of family hauling and stop-and-go commuting, this direct-fit ignition package restores factory combustion balance, protects downstream emissions components, and ensures immediate cold-start reliability without ECU tuning.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50606017216760,"sku":"DS-EBYZ1K6YS","price":76.95,"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-sedona-2002-2005-3-5l-1.jpg?v=1790090153","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-kia-sedona-2002-2005-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
