Incomplete combustion and oil blow-by contaminate the precious metal matrix, leading to reduced exhaust flow, restrictive thermal choking, sluggish throttle response, and persistent P0420\/P0430 diagnostic trouble codes under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement assembly utilizes a high-grade 409 stainless steel outer casing that resists road debris impacts, thermal expansion stress, and corrosion. Inside, a durable, high-efficiency ceramic honeycomb monolith delivers optimal surface area for exhaust gas conversion without creating parasitic backpressure. CNC-machined direct-fit flanges and precision-welded pre- and post-catalyst O2 sensor bungs ensure a leak-free, bolt-on replacement matching OEM geometry.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2004-2008 Ford F-150\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eModular 4.6L 2V V8 \/ P221\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e231-248 hp \/ 280-294 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e30539, 794188, 0794187, 19266, 30540\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2004-2008 Ford F-150\u003c\/strong\u003e – 4.6L V8 (Left \/ Driver Side Placement)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Ford Truck Caliber\u003c\/h3\u003e\n\u003cp\u003eBuilt to withstand the high thermal loads of daily work and heavy towing, this converter preserves critical low-end torque while eliminating exhaust leaks and check engine lights for long-term reliability.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50464852050168,"sku":"DS-E12BU4D8H","price":129.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-ford-f-150-2004-2008-4-6l-1.jpg?v=1788889070","url":"https:\/\/performancechiptuning.com\/es\/products\/catalytic-converter-for-ford-f-150-2004-2008-4-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
