Over time, the internal ceramic monolith substrate experiences washcoat erosion, leading to diminished hydrocarbon reduction and elevated exhaust backpressure. This restriction chokes exhaust scavenging on the \u003cstrong\u003e4.0L Cologne SOHC V6\u003c\/strong\u003e, triggering persistent check engine lights (CEL), reducing fuel efficiency, and causing upstream exhaust flange leaks under heavy engine load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eBuilt with a heavy-gauge stainless steel casing and high-efficiency ceramic honeycomb monolith, this direct-fit rear converter assembly restores stoichiometric conversion efficiency. Precision laser-cut flanges match factory downstream junction points to eliminate exhaust blow-by without cutting or welding. Optimized cell density ensures compliant exhaust scrubbing while lowering backpressure, protecting the valvetrain of the \u003cstrong\u003e4.0L Cologne V6\u003c\/strong\u003e during heavy towing operations.\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;\"\u003e2007-2010 Ford Explorer Sport Trac\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;\"\u003e4.0L Cologne SOHC V6 \/ U251\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;\"\u003e6L2Z5F250A, 6L2Z5F250AB, 16434, 30460, 645430\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\u003e2007 Ford Explorer Sport Trac 4.0L V6 (Rear)\u003c\/li\u003e\n  \u003cli\u003e2008 Ford Explorer Sport Trac 4.0L V6 (Rear)\u003c\/li\u003e\n  \u003cli\u003e2009 Ford Explorer Sport Trac 4.0L V6 (Rear)\u003c\/li\u003e\n  \u003cli\u003e2010 Ford Explorer Sport Trac 4.0L V6 (Rear)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the U251 Explorer Sport Trac?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2007-2010 Ford Explorer Sport Trac equipped with the \u003cstrong\u003e4.0L Cologne SOHC V6\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eWill this converter clear downstream catalyst efficiency trouble codes?\u003c\/h4\u003e\n\u003cp\u003eYes, it restores stoichiometric reduction capacity to clear P0420 and P0430 DTCs without ECM reprogramming.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Utility Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle the towing loads and sustained exhaust gas temperatures of the \u003cstrong\u003eU251\u003c\/strong\u003e mid-size truck platform, this replacement provides reliable emissions compliance and structural rigidity across demanding hauling duties.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67537828937976,"sku":"DS-EZE44YF57","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-sport-trac-2007-2010-4-0l-rear-1.jpg?v=1790617939","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-ford-explorer-sport-trac-2007-2010-4-0l-rear","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
