The factory front catalyst on the \u003cstrong\u003e1NZ-FE\u003c\/strong\u003e engine is subject to thermal fatigue and exhaust washcoat sintering over extended heat cycles. Over time, oil blow-by and carbon accumulation foul the factory ceramic core, inducing cell clogging and internal matrix breakdown. This breakdown spikes exhaust backpressure, chokes high-RPM volumetric efficiency, and triggers persistent P0420 catalytic deficiency trouble codes that fail state emissions inspections.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis front direct-fit assembly is engineered to restore proper flow dynamics and catalytic function. Fabricated with a robust 409 stainless steel outer shell, the unit resists external corrosion and thermal stress cracking. Inside, a flow-optimized ceramic honeycomb substrate is coated with an active washcoat of precious metals to maximize chemical conversion of HC, CO, and NOx while minimizing backpressure. Thick, precision-machined direct-fit flanges ensure leak-free sealing at the factory manifold and mid-pipe joints, retaining OE sensor bungs for true plug-and-play installation.\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;\"\u003e2004-2006 Scion xA\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;\"\u003e1NZ-FE (1.5L) \/ NCP61\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;\"\u003e108 hp \/ 105 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;\"\u003e16339, 51231\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\u003e2004 Scion xA Base Hatchback 1.5L L4 (1NZ-FE \/ NCP61) - Front\u003c\/li\u003e\n  \u003cli\u003e2005 Scion xA Base Hatchback 1.5L L4 (1NZ-FE \/ NCP61) - Front\u003c\/li\u003e\n  \u003cli\u003e2006 Scion xA Base Hatchback 1.5L L4 (1NZ-FE \/ NCP61) - Front\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the NCP61 xA?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct bolt-on replacement for the 2004-2006 Scion xA equipped with the 1.5L \u003cstrong\u003e1NZ-FE\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eWill this clear the P0420 catalytic efficiency diagnostic trouble code?\u003c\/h4\u003e\n\u003cp\u003eYes, provided upstream fueling and secondary oxygen sensors are functioning within factory specifications, this unit restores proper conversion efficiency to clear P0420 codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Scion JDM Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-revving \u003cstrong\u003e1NZ-FE\u003c\/strong\u003e applications, this assembly balances unrestricted exhaust velocity with strict tailpipe scrubbing, preserving the crisp throttle response and clean combustion characteristics expected from the compact JDM platform.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67537743479032,"sku":"DS-E82B9PISR","price":177.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-scion-xa-2004-2006-1-5l-front-1.jpg?v=1790616699","url":"https:\/\/performancechiptuning.com\/es\/products\/catalytic-converter-for-scion-xa-2004-2006-1-5l-front","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
