Over extended drive cycles, direct-injection carbon fouling and excessive exhaust gas temperatures cause the dense OEM ceramic honeycomb washcoat to sinter, melt, or structurally crumble. This thermal stress elevates exhaust backpressure, restricts scavenging dynamics, triggers lingering check engine lights (DTC P0420), and risks downstream engine damage from ceramic dust ingestion during valve overlap.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a bolt-on assembly matching OEM casting geometries, this direct-replacement unit features heavy-gauge stainless steel tubing and durable flange plates to mitigate thermal warping. Inside, a high-efficiency ceramic substrate formulated with an optimized precious-metal catalytic washcoat ensures rapid light-off temperatures and precise gas-to-surface reduction without inducing flow bottlenecks. Precision robotically welded seams prevent exhaust leaks, while the CNC-machined factory-located oxygen sensor bung preserves standard harness routing and sensor depth to ensure accurate closed-loop ECU AFR trimming.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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;\"\u003e2015-2018 Kia Sedona (Front Bank)\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;\"\u003e285103CHW0, 285103CCI0, 41111, 52780, 641474, 674-258\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2015 Kia Sedona L, LX, EX, SX, SX Limited 3.3L V6 (Front)\u003c\/li\u003e\n  \u003cli\u003e2016 Kia Sedona L, LX, EX, SX, SX Limited 3.3L V6 (Front)\u003c\/li\u003e\n  \u003cli\u003e2017 Kia Sedona L, LX, EX, SX, SX Limited 3.3L V6 (Front)\u003c\/li\u003e\n  \u003cli\u003e2018 Kia Sedona L, LX, EX, SX 3.3L V6 (Front)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the YP Sedona?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2015-2018 Kia Sedona equipped with the Lambda II 3.3L G6DH engine.\u003c\/p\u003e\n\n\u003ch4\u003eIs this catalytic converter legal for use in California or CARB-compliant states?\u003c\/h4\u003e\n\u003cp\u003eNo, this unit is 46-state EPA compliant and cannot be sold, shipped, or installed on vehicles registered in California, New York, Colorado, or Maine.\u003c\/p\u003e\n\n\u003ch3\u003eThe Kia Durability Standard\u003c\/h3\u003e\n\u003cp\u003eDesigned to handle everyday family hauling and continuous highway loading, this assembly provides heat resilience and structural durability that keep your minivan running smoothly with zero exhaust leaks.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67538069225720,"sku":"DS-ET3GQ7X2L","price":386.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-kia-sedona-2015-2018-3-3l-front-1.jpg?v=1790621970","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-kia-sedona-2015-2018-3-3l-front","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
