This internal attrition causes substrate sintering or partial cell collapse, creating severe exhaust backpressure that chokes out the \u003cstrong\u003e4.0L Cologne V6\u003c\/strong\u003e engine under towing loads. Furthermore, depleted precious metal loading fails to neutralize secondary unburned hydrocarbons and carbon monoxide, triggering persistent catalyst efficiency check engine lights and failing tailpipe emissions inspections.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis rear catalytic converter assembly features a high-grade 409 stainless steel outer shell engineered to resist road salt pitting, road debris punctures, and extreme exhaust thermal cycling. Inside, a heavy-duty ceramic honeycomb substrate is coated with an optimized formulation of platinum, palladium, and rhodium washcoat to restore factory conversion efficiency without throttling scavenging speed. Built to original geometry, this direct-replacement unit retains factory flange positions and slip-fit joints, ensuring exact alignment with the OEM intermediate pipe and stock mounting hangers without custom torch work or tube expansion.\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: solid font-size: min-width:\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;\"\u003e2006-2010 Ford Explorer\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;\"\u003e\n\u003cstrong\u003e4.0L Cologne SOHC V6\u003c\/strong\u003e \/ \u003cstrong\u003eU251\u003c\/strong\u003e\n\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;\"\u003e210 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;\"\u003e\n\u003cstrong\u003e6L2Z5F250A\u003c\/strong\u003e, \u003cstrong\u003e6L2Z5F250AB\u003c\/strong\u003e, \u003cstrong\u003e16434\u003c\/strong\u003e, \u003cstrong\u003e30460\u003c\/strong\u003e, \u003cstrong\u003e645430\u003c\/strong\u003e\n\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\u003e2006 Ford Explorer 4.0L V6 (Eddie Bauer, Limited, XLS, XLT)\u003c\/li\u003e\n  \u003cli\u003e2007 Ford Explorer 4.0L V6 (Eddie Bauer, Limited, XLT)\u003c\/li\u003e\n  \u003cli\u003e2008 Ford Explorer 4.0L V6 (Eddie Bauer, Limited, XLT)\u003c\/li\u003e\n  \u003cli\u003e2009 Ford Explorer 4.0L V6 (Eddie Bauer, Limited, XLT)\u003c\/li\u003e\n  \u003cli\u003e2010 Ford Explorer 4.0L V6 (Eddie Bauer, Limited, XLT)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the U251 Explorer?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2006-2010 Ford Explorer equipped with the \u003cstrong\u003e4.0L Cologne V6\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eIs this catalytic converter CARB-approved for California?\u003c\/h4\u003e\n\u003cp\u003eNo, this assembly is EPA 48-state compliant and cannot be legally shipped to or installed on vehicles registered in California, New York, Colorado, or Maine.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Utility Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle rigorous duty cycles and towing loads, this heavy-gauge stainless converter maintains uncompromised structural integrity and sustained exhaust throughput under demanding operating conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67537821466872,"sku":"DS-EF3GFB16O","price":248.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-ford-explorer-2006-2010-4-0l-rear-3.jpg?v=1790617868","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-ford-explorer-2006-2010-4-0l-rear","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
