Over time, the internal ceramic monolith substrate in the factory converters experiences washcoat degradation, core sintering, and thermal shock fractures. This deterioration reduces exhaust flow velocity, creates elevated backpressure against the **Duratec 35** cylinder heads, and triggers persistent check engine lights for catalyst system efficiency below threshold (P0420 and P0430).\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a bolt-on solution for Bank 1 and Bank 2 exhaust banks, these direct-replacement converters feature heavy-gauge stainless steel tubing with robotic TIG welds for structural integrity under high exhaust gas temperatures. The high-efficiency ceramic honeycomb cores provide optimal precious metal washcoat dispersion, ensuring swift light-off times and proper reduction of HC, CO, and NOx without restricting flow. Thick OE-spec laser-cut flanges match factory port geometry perfectly, guaranteeing a leak-free seal to standard cylinder heads and intermediate flex pipes.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Front Right \/ Bank 1 Manifold Catalytic Converter (Firewall Side)\u003c\/li\u003e\n  \u003cli\u003e1x Front Left \/ Bank 2 Manifold Catalytic Converter (Radiator Side)\u003c\/li\u003e\n  \u003cli\u003e1x Installation Accessory Hardware \u0026amp; Gasket Kit\u003c\/li\u003e\n\u003c\/ul\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;\"\u003e2013-2019 Ford Flex, Taurus\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;\"\u003eDuratec 35 3.5L V6 \/ D3\/D4\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;\"\u003e288 hp \/ 254 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;\"\u003e674256, 674255, 1378, 1379, 19516, 19517, 30584, 30585\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\u003e2013-2019 Ford Flex 3.5L V6 (Naturally Aspirated)\u003c\/li\u003e\n  \u003cli\u003e2013-2019 Ford Taurus 3.5L V6 (Naturally Aspirated)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the D3\/D4 Flex and Taurus?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2013-2019 Ford Flex and Taurus equipped with the naturally aspirated **Duratec 35** 3.5L engine. \u003cstrong\u003eNot compatible with 3.5L EcoBoost twin-turbocharged models or vehicles requiring California, New York, Colorado, or Maine emissions compliance.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eIs this unit emissions legal nationwide?\u003c\/h4\u003e\n\u003cp\u003eThis replacement set is 46-state EPA compliant and cannot be sold, shipped, or installed on vehicles registered in CARB emissions states (CA, NY, CO, ME).\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Fleet-Grade Durability Caliber\u003c\/h3\u003e\n\u003cp\u003eDesigned to handle the demands of rigorous daily commuting and sustained highway hauling, this manifold converter assembly delivers heavy-duty service life and exact emission sensor compatibility without check engine light reactivation.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67563052007672,"sku":"DS-E6VXYR7ZX","price":153.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-ford-flex-taurus-2013-2019-3-5l-front-left-right-1.jpg?v=1790999875","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-ford-flex-taurus-2013-2019-3-5l-front-left-right","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
