The factory \u003cstrong\u003eEGJ 3.5L SOHC V6\u003c\/strong\u003e operates under high exhaust gas temperatures during sustained load, accelerating the thermal sintering of the internal precious metal washcoat. Over time, physical washcoat breakdown leads to reduced oxygen storage capacity (OSC), triggering recurring catalyst efficiency failure codes. Additionally, road debris and engine thermal expansion cause fatigue at the original mild steel flange welds, resulting in micro-fissures, exhaust leaks upstream of downstream O2 sensors, and loss of scavenging velocity.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement assembly incorporates a heavy-gauge \u003cstrong\u003e409 stainless steel\u003c\/strong\u003e outer shell designed to resist road salt corrosion and severe thermal cycling. Inside, a high-density, flow-optimized \u003cstrong\u003ehoneycomb ceramic substrate\u003c\/strong\u003e features a robust chemical washcoat that ensures rapid light-off and reliable emissions reduction without creating excessive backpressure. Engineered to mount directly into factory hangers and mating flanges, it includes precision-cut mounting hardware, a replacement clamp, and heavy-duty composite exhaust gaskets. The direct-fit geometry retains proper downstream oxygen sensor orientation, preventing wiring harness strain while restoring smooth exhaust gas evacuation across the mid-range power band.\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;\"\u003e2004-2006 Chrysler Pacifica\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;\"\u003e3.5L SOHC 24V V6 (EGJ) \/ CS Platform\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;\"\u003e250 hp \/ 250 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;\"\u003e642279\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2004 Chrysler Pacifica Base 3.5L V6 (FWD \/ AWD)\u003c\/li\u003e\n  \u003cli\u003e2005 Chrysler Pacifica Base 3.5L V6 (FWD \/ AWD)\u003c\/li\u003e\n  \u003cli\u003e2005 Chrysler Pacifica Limited 3.5L V6 (FWD \/ AWD)\u003c\/li\u003e\n  \u003cli\u003e2005 Chrysler Pacifica Touring 3.5L V6 (FWD \/ AWD)\u003c\/li\u003e\n  \u003cli\u003e2006 Chrysler Pacifica Base 3.5L V6 (FWD \/ AWD)\u003c\/li\u003e\n  \u003cli\u003e2006 Chrysler Pacifica Limited 3.5L V6 (FWD \/ AWD)\u003c\/li\u003e\n  \u003cli\u003e2006 Chrysler Pacifica Touring 3.5L V6 (FWD \/ AWD)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the CS Pacifica?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2004-2006 Chrysler Pacifica equipped with the 3.5L SOHC EGJ engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this catalytic converter legal for road use in California?\u003c\/strong\u003e\u003cbr\u003e This EPA-compliant unit is not CARB-approved and cannot be sold, shipped, or installed on vehicles registered in California or CARB-restricted states.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chrysler Fleet Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-mileage family haulers and daily utility, this replacement converter delivers the long-term durability, structural integrity, and leak-free reliability needed to handle heavy loads, daily commutes, and demanding road conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50501697044728,"sku":"DS-E4YNE90LE","price":191.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-chrysler-pacifica-2004-2006-3-5l-1.jpg?v=1789329624","url":"https:\/\/performancechiptuning.com\/es\/products\/catalytic-converter-for-chrysler-pacifica-2004-2006-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
