The original ceramic substrate degrades, causing matrix fracture, washcoat erosion, or complete core meltdown.

The high-porosity washcoat is loaded with precious metal catalysts to maximize hydrocarbon and carbon monoxide conversion rates without restricting exhaust gas velocity. Precision-cut, thick-gauge mounting flanges prevent thermal warping and exhaust leaks at the cylinder head interface, while factory-located oxygen sensor bungs preserve closed-loop fuel feedback. Supplied with replacement seals and hardware, this bolt-on kit eliminates the need for cutting or custom fabrication.\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; margin-bottom: 20px;\"\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;\"\u003e2002-2004 Nissan Frontier, Xterra 3.3L\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\u003eVG33E\u003c\/strong\u003e \/ \u003cstrong\u003eD22\u003c\/strong\u003e, \u003cstrong\u003eWD22\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;\"\u003e180 hp \/ 202 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;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2002-2004 Nissan Frontier (3.3L V6 VG33E \/ D22 Chassis)\u003c\/li\u003e\n  \u003cli\u003e2002-2004 Nissan Xterra (3.3L V6 VG33E \/ WD22 Chassis)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the D22 and WD22 Frontier and Xterra?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2002-2004 Nissan Frontier and Xterra equipped with the 3.3L \u003cstrong\u003eVG33E\u003c\/strong\u003e naturally aspirated engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this converter assembly resolve downstream oxygen sensor check engine lights?\u003c\/strong\u003e\u003cbr\u003e Yes, its active ceramic washcoat restores catalytic conversion efficiency to extinguish catalyst-related \u003cstrong\u003eP0420\u003c\/strong\u003e and \u003cstrong\u003eP0430\u003c\/strong\u003e trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan Truck \u0026amp; Utility Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to withstand the vibration, frame flex, and severe heat loads encountered in commercial towing and off-road driving, this heavy-duty converter maintains structural integrity under sustained thermal stress.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50502067880184,"sku":"DS-EUW0QCHFU","price":307.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-nissan-frontier-xterra-2002-2004-3-3l-front-left-right-1.jpg?v=1789335754","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-nissan-frontier-xterra-2002-2004-3-3l-front-left-right","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
