This Lambda / Oxygen (O₂) Sensor, OE Part Number 39210-22610, is a genuine Hyundai and Kia original equipment component engineered for precise air-fuel ratio monitoring. Manufactured to factory specifications, this 4-wire heated sensor delivers reliable emissions control and fuel efficiency across a wide range of Hyundai and Kia petrol vehicles.

• 4-wire heated oxygen sensor manufactured to Hyundai and Kia original equipment standards for dependable performance.
• The built-in heating element rapidly brings the ceramic sensing tip to operating temperature after a cold start, allowing the ECU to enter closed-loop fuel control sooner and reducing cold-start emissions.
• Features an oval 4-pin connector with a black socket and a cable length ranging from approximately 330 mm to 380 mm depending on the aftermarket manufacturer.
• Threads are factory pre-greased for quick and easy installation.
• Position note: Documented as a front (upstream / pre-catalyst) sensor for many applications, but also listed as a downstream (post-catalyst) sensor for others (e.g., Kia Spectra). Always verify the position of your original sensor before ordering.

The following OE numbers are directly interchangeable or closely related to 39210-22610. These references are frequently grouped together across multiple aftermarket catalogues.

• Vemo V52-76-0004 lists 39210-22610 as an OE reference, along with 39210-22600, 39210-23750, 39210-23950, and several other related numbers, with a 330 mm cable length and oval connector.
• ABAKUS 120-08-063 (manufactured by LORO) lists 39210-22610 as the OE reference, with a 375 mm cable length, 4 conductors, 4-pin connector, and M18 × 1.5 thread.
• HERTH+BUSS JAKOPARTS J1460332 and METZGER 0893014 are also documented aftermarket equivalents for this OE number.
• 234-4851, 13461, and SG1695 are common aftermarket interchange numbers used by various suppliers for this sensor.
• Always physically compare your old sensor's connector shape (oval), pin count (4), cable length (330–380 mm), and thread size (M18 × 1.5) before purchasing.

This Lambda Sensor is an original equipment component used across a wide range of Hyundai and Kia vehicles. Based on available cross-reference data, it is compatible with the following applications.

• This sensor is compatible with a large number of vehicle variants (over 1,900 according to one compatibility listing).
• Primary applications include Hyundai Accent, Elantra, Tiburon, Tucson, and Getz; Kia Rio, Rio5, Spectra, Spectra5, Cerato, and Sportage with 1.4L, 1.5L, 1.6L, and 2.0L petrol engines.
• Position varies by application: For Kia Spectra / Spectra5, this sensor is listed as a downstream (post-catalyst) sensor. For many Hyundai applications, it is also used as a front (upstream / pre-catalyst) sensor.
• How to verify: Locate your vehicle's catalytic converter. The upstream sensor is installed before the converter; the downstream sensor is installed after the converter. Check the position of your original sensor before ordering.
• Not compatible with diesel engines — diesel applications use different sensors with different calibration parameters.
• The vehicle fitment information above is a guide only. Always confirm compatibility using your vehicle's VIN or by physically inspecting your old sensor's position, connector shape, and cable length before ordering.
