In the \u003cstrong\u003e2UZ-FE\u003c\/strong\u003e 4.7L V8, degraded exhaust bricks choke cylinder scavenging, creating severe backpressure that robs low-end torque and triggers persistent P0420 diagnostic trouble codes. Neglected thermal breakdown can lead to partial substrate collapse, compromising exhaust velocity and elevating exhaust gas temperatures under heavy load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact OEM dimensional specifications, this front right direct-fit catalytic converter replaces the worn factory assembly without cutting or welding. Constructed with a heavy-gauge stainless steel casing and precision-aligned flanges, it provides superior resistance to thermal fatigue and stress cracking. Inside, a high-efficiency ceramic honeycomb substrate features a dense precious metal washcoat that chemically converts harmful carbon monoxide, hydrocarbons, and nitrogen oxides into EPA-compliant tailpipe emissions while restoring full exhaust throughput.\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;\"\u003e2003-2005 Lexus GX\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\u003e2UZ-FE\u003c\/strong\u003e \/ \u003cstrong\u003eUZJ120\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;\"\u003e235 - 270 hp \/ 320 - 330 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\u003e2003 Lexus GX470 Base Sport Utility 4-Door 4.7L 4663CC V8 GAS DOHC Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e2004 Lexus GX470 Base Sport Utility 4-Door 4.7L 4663CC V8 GAS DOHC Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e2005 Lexus GX470 Base Sport Utility 4-Door 4.7L 4663CC V8 GAS DOHC Naturally Aspirated\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the UZJ120 GX?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2003-2005 Lexus GX equipped with the \u003cstrong\u003e2UZ-FE\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this clear a catalyst system efficiency (P0420) check engine light?\u003c\/strong\u003e\u003cbr\u003e Yes, installing this EPA-compliant converter restores factory conversion efficiency to resolve diagnostic trouble codes associated with substrate degradation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Lexus GX Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for the heavy mechanical demands of full-frame utility platforms, this converter assembly resists thermal warping, off-road vibration, and high-load towing heat to ensure long-term durability on and off the pavement.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50502197444856,"sku":"DS-E2972FMPR","price":211.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-lexus-gx-2003-2005-4-7l-front-right-1.jpg?v=1789339264","url":"https:\/\/performancechiptuning.com\/es\/products\/catalytic-converter-for-lexus-gx-2003-2005-4-7l-front-right","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
