NTK 25678 oxygen sensor for the 2007-2009 Kia Sorento V6 3.8L, the 2008-2009 Sorento V6 3.3L and other vehicles gives the ECU constant closed-loop feedback to help control the air-fuel ratio. The ceramic element in this NTK oxygen sensor is controlled from raw material to finished product.
- Heated switching zirconia sensing element
- 3-stage contaminant-resistant plasma jet and deposit trap overcoat that protects the element against poisoning
- Dual-coated platinum interface and thinner ceramic element for fast light-off and response times
- Vibration and thermal shock testing during development, plus testing during manufacturing
Quick facts
- Part: NTK 25678 oxygen sensor
- Fits: the 2007-2009 Kia Sorento V6 3.8L, the 2008-2009 Sorento V6 3.3L and other vehicles
- Position: Upstream left, upstream right
- Condition: New
A check engine light, rough running or poorer fuel economy can mean the oxygen sensor is worn, though a failing catalytic converter or a leaking fuel injector can be behind the same signs, so find the cause first. This listing is one sensor; the 2007-2009 Kia Sorento V6 3.8L takes one.
Fits
The vehicles it fits include the 2007-2009 Hyundai Santa Fe V6 3.3L and the 2007-2012 Hyundai Veracruz V6 3.8L, along with the Sorento runs above. If your car is not named here, open the "Vehicles it fits" section and look up your exact model and engine.

Frequently Asked Questions
Is this the right oxygen sensor for a 2007-2009 Kia Sorento V6 3.8L?
Yes. NTK 25678 fits the 2007-2009 Kia Sorento V6 3.8L and the 2008-2009 Sorento V6 3.3L. Open the "Vehicles it fits" section to check other models and engines.
Does NTK 25678 come with connectors and harness hardware?
Yes. This sensor is equipped with water-resistant connectors and harness accessory hardware for installation.
Is this NTK O2 sensor heated?
Yes. NTK 25678 is a heated switching zirconia sensor with a 7/8" (22mm) hex size.
How are NTK sensors tested?
Development includes vibration and thermal shock testing, and the sensors are tested again during manufacturing.
Can a worn upstream oxygen sensor turn on the check engine light?
Yes, it can. The sensor feeds the ECU, and OBDII systems flag possible fuel delivery or catalytic converter efficiency problems. A shop can read the code to find the cause.
