NGK O2 SENSORS 25158 sensor for the 2003-2006 Kia Sorento 3.5L and other vehicles is an oxygen sensor that gives the ECU constant closed-loop feedback to help control the air-fuel ratio. It also alerts the OBDII system to possible fuel delivery or catalytic converter problems.

  • Product line: NTK OE Type Oxygen Sensor
  • NTK is the world's largest supplier of original equipment oxygen sensors, with quality that meets or exceeds OEM specifications
  • Based on OE expertise and engineered for the aftermarket, with OE fit, form and function and the latest OE technologies to reduce OE failures
  • OE development includes vibration and thermal shock testing, and testing during manufacturing
  • 3-stage contaminant-resistant plasma jet and a deposit trap overcoat protect the ceramic element against poisoning
  • Dual-coated platinum interface and a thinner ceramic element give the fastest light-off and response times

A failing sensor can show up as a check engine light, rough running or poorer fuel economy. A vacuum leak, a worn catalytic converter or a fuel delivery fault can also be behind those signs, so find the cause before buying a sensor.

This part number also covers sensors for the 2003-2006 Hyundai Santa Fe 3.5L and 2004-2006 Kia Amanti 3.5L, along with other vehicles. A 2003-2006 Kia Sorento 3.5L takes one sensor. If your car is not named here, look it up on the Buyer's Guide tab.
