Factory coil packs suffer progressive dielectric breakdown as thermal cycling degrades the internal epoxy insulation and primary windings. This leads to secondary voltage leakage, erratic resistance spikes, and severe misfires under load (typically throwing DTCs P0300 through P0306). Simultaneously, standard spark plug electrodes erode rapidly under high-pressure direct injection, widening the gap and straining aged coils to the point of complete ignition failure.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct replacement service kit includes six heavy-duty pencil coils and six laser-welded iridium spark plugs designed to withstand high-duty cycles. The coil housings use high-dielectric reinforced thermoplastic and premium copper wire windings potted in high-grade epoxy to prevent arcing and thermal degradation up to 140°C. Paired with 0.6mm fine-wire iridium center electrode plugs, the system requires lower discharge voltage to spark, producing a stable flame kernel that burns cleanly across direct-injection spray patterns while directly matching OEM \u003cstrong\u003e273103L000\u003c\/strong\u003e and \u003cstrong\u003eUF844\u003c\/strong\u003e specifications.\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;\"\u003e2018-2020 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;\"\u003e3.3L Lambda II GDI (G6DH) \/ YP\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;\"\u003e276 hp \/ 248 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;\"\u003e273103L000, UF844, KIN133746TOP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2018 Kia Sedona (L, LX, EX, SX, SX Limited 3.3L V6)\u003c\/li\u003e\n  \u003cli\u003e2019 Kia Sedona (L, LX, EX, SX 3.3L V6)\u003c\/li\u003e\n  \u003cli\u003e2020 Kia Sedona (L, LX, EX, SX 3.3L V6)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the YP Sedona?\u003c\/strong\u003e\u003cbr\u003e Yes, this kit is a direct bolt-in fit for all 2018-2020 Kia Sedona models equipped with the 3.3L \u003cstrong\u003eLambda II GDI\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre the included iridium spark plugs pre-gapped?\u003c\/strong\u003e\u003cbr\u003e Yes, the spark plugs come pre-gapped to factory specification (0.040–0.044 in) for immediate installation without manual re-gapping.\u003c\/p\u003e\n\n\u003ch3\u003eThe Kia High-Mileage Caliber\u003c\/h3\u003e\n\u003cp\u003eBuilt for the continuous demands of passenger hauling and long-distance road trips, this ignition kit restores the factory-level combustion reliability and fuel efficiency required to keep your powertrain running smoothly without uncommanded engine check lights.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50594142978296,"sku":"DS-EBC3S24YK","price":158.95,"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-2018-2020-3-3l-1.jpg?v=1790057366","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-kia-sedona-2018-2020-3-3l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
