Over extended mileage, continuous thermal cycling, carbon accumulation, and unburnt hydrocarbon spikes degrade the factory ceramic washcoat. This degradation leads to restricted exhaust flow, increased backpressure, degraded fuel economy, and recurring check engine lights driven by catalyst efficiency failure.\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, this direct-fit catalytic converter set features robust stainless steel tubing and heavy-gauge flanges designed to resist thermal warping. The upgraded internal monolith optimizes precious metal loading for efficient emissions reduction without creating excessive backpressure. Precision automated welds secure the collector junctions, providing long-term structural integrity and direct alignment with factory downpipe connections matching OE references \u003cstrong\u003e674256\u003c\/strong\u003e and \u003cstrong\u003e674255\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Front Left (Bank 2) Catalytic Converter Manifold\u003c\/li\u003e\n  \u003cli\u003e1x Front Right (Bank 1) Catalytic Converter Manifold\u003c\/li\u003e\n  \u003cli\u003eInstallation Hardware and Gasket Accessories Set\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;\"\u003e2013-2018 Lincoln MKT\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;\"\u003eCyclone 3.7L Ti-VCT \/ 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;\"\u003e303 hp \/ 278 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 Lincoln MKT 3.7L V6\u003c\/li\u003e\n  \u003cli\u003e2014 Lincoln MKT 3.7L V6\u003c\/li\u003e\n  \u003cli\u003e2015 Lincoln MKT 3.7L V6\u003c\/li\u003e\n  \u003cli\u003e2016 Lincoln MKT 3.7L V6\u003c\/li\u003e\n  \u003cli\u003e2017 Lincoln MKT 3.7L V6\u003c\/li\u003e\n  \u003cli\u003e2018 Lincoln MKT 3.7L V6\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 D4 MKT?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2013-2018 Lincoln MKT equipped with the \u003cstrong\u003eCyclone 3.7L\u003c\/strong\u003e engine.
