Paired with twin-turbocharged heat loading from the \u003cstrong\u003e3.5L EcoBoost\u003c\/strong\u003e, prolonged towing stresses the original honeycomb structure. Over time, high exhaust gas temperatures cause substrate sintering and localized melt-through, causing elevated exhaust backpressure, lost spool efficiency, and persistent P0420 and P0430 diagnostic trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis left and right converter assembly is engineered with mandrel-bent stainless steel tubing and robust, precision-cut flanges that match OEM exhaust geometry without requiring custom fabrication. High-flow ceramic internal substrates provide dense surface area for optimal emissions reduction, allowing the engine management system to maintain precise closed-loop fueling control. Integrated factory-positioned oxygen sensor bungs retain stock sensor harnesses, ensuring proper downstream monitoring and unrestrained turbocharger discharge flow.\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;\"\u003e2015-2017 Ford Expedition\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 EcoBoost V6 \/ U324\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;\"\u003e365 hp \/ 420 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;\"\u003eFL1Z-5E212-A, 19717, 19718, 59737, 59738, 645150, 645151\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 Ford Expedition 3.5L EcoBoost V6 (XLT, Limited, King Ranch, Platinum)\u003c\/li\u003e\n  \u003cli\u003e2016 Ford Expedition 3.5L EcoBoost V6 (XLT, Limited, King Ranch, Platinum)\u003c\/li\u003e\n  \u003cli\u003e2017 Ford Expedition 3.5L EcoBoost V6 (XLT, Limited, King Ranch, Platinum)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the U324 Expedition?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2015-2017 Ford Expedition equipped with the 3.5L EcoBoost engine.\u003c\/p\u003e\n\n\u003ch4\u003eWill this resolve catalyst efficiency DTCs like P0420 and P0430?\u003c\/h4\u003e\n\u003cp\u003eYes, this dual converter set restores necessary precious metal conversion volume to bring emissions readings back within factory OBD-II thresholds.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Towing Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe duty towing cycles and high exhaust gas temperatures, this direct-fit stainless assembly ensures durable exhaust management and dependable full-throttle boost retention under heavy loads.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67538059264248,"sku":"DS-E5MACBRLI","price":373.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-ford-expedition-2015-2017-3-5l-left-right-1.jpg?v=1790621592","url":"https:\/\/performancechiptuning.com\/es\/products\/catalytic-converter-for-ford-expedition-2015-2017-3-5l-left-right","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
