Under continuous thermal cycling, the internal ceramic monolith degrades, while persistent unburnt hydrocarbons and oil vapor from aging \u003cstrong\u003e4.6L Modular V8\u003c\/strong\u003e valve guides coat the precious metal washcoat. This contamination chokes exhaust gas velocity, increases cylinder head backpressure, spikes exhaust gas temperatures, and inevitably triggers efficiency-related Check Engine Lights.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact OEM geometric tolerances, this direct-fit driver-side catalytic assembly utilizes heavy-gauge aluminized steel tubing to resist road salt pitting, corrosion, and structural heat stress. The high-efficiency ceramic honeycomb substrate is loaded with a high-density catalytic washcoat designed to rapidly oxidize carbon monoxide and unburnt hydrocarbons while reducing nitrogen oxides. Precision-machined, mandrel-bent piping maintains uniform diameter through bends to clear 4WD front driveshafts and crossmembers, while factory-style flanges ensure an airtight seal to OE manifolds using references \u003cstrong\u003e30358\u003c\/strong\u003e and \u003cstrong\u003e794120\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;\"\u003e1997-1998 Ford F-250 (4WD)\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;\"\u003e4.6L Modular V8 \/ PN96\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;\"\u003e220 hp \/ 290 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;\"\u003e30358, 794120\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\u003e1997-1998 Ford F-250 Base \/ XL \/ XLT (4WD Models, 4.6L V8 Only, Left\/Driver Side)\u003c\/li\u003e\n  \u003cli\u003eFitment Note: Excludes 2WD configurations and 5.4L Triton V8 engines.\u003c\/li\u003e\n  \u003cli\u003eEmissions Standard: 46-State EPA compliant (Not legal for sale or use in CA, NY, CO, or ME).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the PN96 F-250?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1997-1998 Ford F-250 equipped with the 4.6L Modular V8 engine and four-wheel drive.\u003c\/p\u003e\n\n\u003ch4\u003eWill this resolve downstream oxygen sensor check engine codes?\u003c\/h4\u003e\n\u003cp\u003eYes, replacing a contaminated or broken factory unit with this catalytic assembly eliminates catalyst efficiency DTCs like P0420 assuming upstream engine management operates properly.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Heavy-Duty Workhorse Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to withstand the elevated continuous exhaust gas temperatures generated under heavy payload hauling, off-road grade climbs, and severe-duty towing conditions typical of Ford utility platforms.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67538077810936,"sku":"DS-ECF4ZXEHV","price":180.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-ford-f-250-1997-1998-4-6l-left-1.jpg?v=1790622257","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-ford-f-250-1997-1998-4-6l-left","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
