Over extended mileage, the factory washcoat degrades and internal ceramic cell walls break down, causing partial melt-down, increased exhaust backpressure, restricted exhaust valve scavenging, and recurring catalytic efficiency check engine lights.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a direct bolt-on manifold assembly, this unit features a heavy-gauge stainless steel tubular runner construction paired with a high-efficiency ceramic honeycomb monolith. The washcoat formulation ensures rapid light-off temperatures and precise stoichiometric chemical conversion of hydrocarbons, NOx, and CO. CNC-machined, laser-cut flanges match factory port geometry to prevent exhaust gas leaks, while precision-placed O2 sensor bungs allow plug-and-play installation without custom fabrication or ECU recalibration.\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;\"\u003e2006-2008 Hyundai Sonata\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\u003eTheta (G4KC)\u003c\/strong\u003e \/ \u003cstrong\u003eNF\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;\"\u003e162 hp \/ 164 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;\"\u003e\u003cstrong\u003eQS414624QR\u003c\/strong\u003e\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\u003e2006 Hyundai Sonata 2.4L L4 Front Position\u003c\/li\u003e\n  \u003cli\u003e2007 Hyundai Sonata 2.4L L4 Front Position\u003c\/li\u003e\n  \u003cli\u003e2008 Hyundai Sonata 2.4L L4 Front Position\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the NF Sonata?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2006-2008 Hyundai Sonata equipped with the \u003cstrong\u003eG4KC\u003c\/strong\u003e 2.4L inline-4 engine.\u003c\/p\u003e\n\n\u003ch4\u003eIs this catalytic converter legal in all 50 states?\u003c\/h4\u003e\n\u003cp\u003eThis is a 48-state legal EPA-compliant converter and cannot be shipped to or registered in California or New York.\u003c\/p\u003e\n\n\u003ch3\u003eThe Hyundai Commuter Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for sustained commuter durability, this manifold catalyst restores peak combustion backpressure, prevents thermal fatigue cracking, and ensures trouble-free engine management compliance under continuous highway driving.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67543947215096,"sku":"DS-E0WJURTXK","price":174.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-hyundai-sonata-2006-2008-2-4l-front-1.jpg?v=1790696201","url":"https:\/\/performancechiptuning.com\/es\/products\/catalytic-converter-for-hyundai-sonata-2006-2008-2-4l-front","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
