Frequent heat-cycling combined with oil-vapor fouling from aging valve guides coats the precious metal washcoat, leading to restricted exhaust flow, increased exhaust gas temperatures, and persistent P0420 diagnostic trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered with a resilient stainless steel exterior canister and an optimized ceramic honeycomb substrate, this direct replacement withstands severe exhaust pulses and high heat cycles. Mandrel-formed transitions reduce boundary layer turbulence, while precision-welded factory-spec flanges and integrated O2 sensor bungs eliminate exhaust leaks and simplify bolt-on installation using the provided hardware and gaskets.\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;\"\u003e2001-2005 Volkswagen Jetta\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;\"\u003e2.0L I4 (AEG \/ AVH \/ AZG \/ BEV \/ BBW) \/ Mk4 (Typ 1J)\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;\"\u003e115 hp \/ 122 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;\"\u003eBER515400\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2001 Volkswagen Jetta 2.0L L4\u003c\/li\u003e\n  \u003cli\u003e2002 Volkswagen Jetta 2.0L L4\u003c\/li\u003e\n  \u003cli\u003e2003 Volkswagen Jetta 2.0L L4\u003c\/li\u003e\n  \u003cli\u003e2004 Volkswagen Jetta 2.0L L4\u003c\/li\u003e\n  \u003cli\u003e2005 Volkswagen Jetta 2.0L L4\u003c\/li\u003e\n  \u003cli\u003eOE \/ Interchange References: 54582, 642766, 49252, 18315, 096-2831, 40435, 19052, 51804, 54850, 19463, 50508\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Volkswagen Precision Caliber\u003c\/h3\u003e\n\u003cp\u003eCalibrated specifically for European engine management profiles, this unit maintains correct secondary oxygen sensor feedback voltage, preventing nuisance check engine lights while preserving smooth low-end torque characteristics.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50488431083768,"sku":"DS-EURY6KPTJ","price":121.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-volkswagen-jetta-2001-2005-2-0l-1.jpg?v=1789149510","url":"https:\/\/performancechiptuning.com\/es\/products\/catalytic-converter-for-volkswagen-jetta-2001-2005-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
