The \u003cstrong\u003eEssex 4.2L V6\u003c\/strong\u003e generates sustained exhaust thermal cycling during heavy hauling, which degrades the original ceramic monolith over time. This leads to carbon fouling, melted cell matrices, increased exhaust backpressure, choked high-RPM cylinder evacuation, and downstream oxygen sensor catalyst efficiency check engine lights.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a bolt-on assembly, this passenger-side unit features heavy-gauge stainless steel construction resistant to thermal expansion cracking and road-salt corrosion. Inside, a high-flow ceramic substrate is washcoated with active precious metals to properly reduce hydrocarbon, NOx, and CO emissions while preserving exhaust flow velocity. Precision-machined, OE-spec flanges and integrated downstream O2 sensor bungs allow direct installation without custom pipe bending or welding, matching factory hanger positions and interchange \u003cstrong\u003e16787\u003c\/strong\u003e.\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;\"\u003e2005-2008 Ford F-150\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;\"\u003e4.2L Essex V6 \/ P221\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;\"\u003e202 hp \/ 260 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;\"\u003e16787\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\u003e2005 Ford F-150 (4.2L V6, Right \/ Passenger Side)\u003c\/li\u003e\n  \u003cli\u003e2006 Ford F-150 (4.2L V6, Right \/ Passenger Side)\u003c\/li\u003e\n  \u003cli\u003e2007 Ford F-150 (4.2L V6, Right \/ Passenger Side)\u003c\/li\u003e\n  \u003cli\u003e2008 Ford F-150 (4.2L V6, Right \/ Passenger Side)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the P221 F-150?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2005-2008 Ford F-150 equipped with the 4.2L Essex V6 engine.\u003c\/p\u003e\n\n\u003ch4\u003eIs this unit legal for sale in CARB-compliant states?\u003c\/h4\u003e\n\u003cp\u003eThis is a 46-state Federal EPA compliant assembly and is not legal for sale, purchase, or installation in California, Colorado, New York, or Maine.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Truck Caliber\u003c\/h3\u003e\n\u003cp\u003eWork-ready trucks demand heavy-duty exhaust components that endure heavy towing weights and rigorous payloads without cracking flanges or failing emissions standards.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67537934614776,"sku":"DS-E79DCUKZH","price":135.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-ford-f-150-2005-2008-4-2l-right-1.jpg?v=1790619732","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-ford-f-150-2005-2008-4-2l-right","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
