By measuring the lambda\/O2 balance further along the exhaust stream, it helps keep the engine’s air–fuel ratio optimal, reducing emissions and supporting steady fuel economy. Equipped with a heating function for rapid warm-up, this sensor delivers accurate readings quickly, improving throttle response and idle stability. A reliable OEM-grade replacement, it fits Kia Optima, Magentis, and Rondo 2.0L models and related Hyundai Sonata 2.4 applications, restoring performance and helping your vehicle pass emissions checks. Crafted to withstand harsh exhaust conditions, this sensor provides durable, long-lasting monitoring where it matters most.\u003c\/p\u003e \u003ch2\u003eBenefits \u0026amp; Tips\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eRestore accurate downstream lambda readings to maintain proper fuel trim and cleaner exhaust. \u003c\/li\u003e \u003cli\u003eImprove idle stability and consistent fuel economy after installation by providing reliable O2 sensor data to the engine control unit.\u003c\/li\u003e \u003cli\u003eChoose this sensor as a precise replacement for worn or faulty downstream sensors on Kia Optima, Magentis, and Rondo 2.0L to maintain optimal performance and emissions compliance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e \u003cli\u003eTip: After installation, allow the engine to reach operating temperature and clear fault codes to ensure the ECU recalibrates with the new sensor.\u003c\/li\u003e \u003cli\u003eTip: When shopping, reference OEM No. 39210-25110 to confirm compatibility with your exact vehicle.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eProduct specifications\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eBrand Name: IWOKPHD\u003c\/li\u003e \u003cli\u003ePart numbers (compatible): 39210-25110, 3921025110, 234-4439, 2344439, 19060387, 2133017, 2133929, SG1697, OS5586, 753895, 25024368, 25183, 15320, AP4-632, 250-24383, OS2534, ES11071\u003c\/li\u003e \u003cli\u003eSensor Type: Piezoelectric\u003c\/li\u003e \u003cli\u003eType: Heating Type\u003c\/li\u003e \u003cli\u003eMeasuring Range: Rear Probe Air Fuel Ratio Lambda Oxygen O2 Sensor\u003c\/li\u003e \u003cli\u003eOEM No.: 39210-25110\u003c\/li\u003e \u003cli\u003eOrigin: Mainland China\u003c\/li\u003e \u003cli\u003eRepeatability: 25183, 15320\u003c\/li\u003e \u003cli\u003eHysteresis: 25183, 15320, AP4-632, 250-24383, OS2534, ES11071\u003c\/li\u003e \u003cli\u003eApplication (selected): For Kia Optima\/Magentis 2.0 2006-2009 (G4KA); For Kia Rondo 2007-2008; For Hyundai Sonata 2.4 2005-2010 (NF) and related variants\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003ePackage includes:\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003e1 x Oxygen Sensor\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eWarnings \/ reminders\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003ePlease check the part number carefully to ensure it matches your vehicle’s requirement.\u003c\/li\u003e \u003cli\u003eIf you’re unsure which item fits your car, send the Part Number(s) or the original product photos to verify compatibility before ordering.\u003c\/li\u003e \u003cli\u003eThe only way to be 100% sure the part fits your vehicle is to compare with your original part.
