Precision dual-layer outer shields protect the porous platinum sensor thimble against thermal shock and exhaust condensation. Factory-molded weather-pack connectors, vehicle-specific wire lengths, and pre-threaded M18x1.5 bodies plug directly into the OEM harness without cutting, pinning, or splicing.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2 Upstream Oxygen Sensors\u003c\/li\u003e\n  \u003cli\u003e2 Downstream Oxygen Sensors\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;\"\u003e1996-2009 Mercury Sable\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;\"\u003e3.0L Vulcan, 3.0L Duratec 30, 3.5L Duratec 35 \/ DN186, D3\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;\"\u003e145-263 hp \/ 170-249 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;\"\u003eSG1813, 234-4001, 234-4046, 234-4070, 234-4071, 234-4127, 234-4401, 22013, 22016, 22060, 22071, 22500\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\u003e1996-2005 Mercury Sable 3.0L V6 (Vulcan \/ Duratec 30)\u003c\/li\u003e\n  \u003cli\u003e2008-2009 Mercury Sable 3.5L V6 (Duratec 35)\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 DN186 and D3 Sable?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1996-2009 Mercury Sable equipped with the \u003cstrong\u003eVulcan 3.0L\u003c\/strong\u003e, \u003cstrong\u003eDuratec 30\u003c\/strong\u003e, or \u003cstrong\u003eDuratec 35\u003c\/strong\u003e engines.
