Direct-Fit Air/Fuel Sensor

The NTK 27025 is a specific-fit air/fuel ratio sensor for select Mitsubishi applications. It is a heated, 5-wire sensor built for accurate exhaust feedback and OE-style fitment. Fits 2014-2016 Mitsubishi Outlander, upstream left.

Key Features

  • Direct Fit 5-Wire A/F Sensor design for specific applications
  • Heated sensor construction for faster operating response
  • 19.0 wiring harness length for application-specific routing
  • 18.000 thread diameter with 0.38 thread length
  • NTK engineering backed by OE-level manufacturing standards

Detailed Description

NTK 27025 is part of the Direct Fit 5-Wire A/F Sensor line, built for vehicles that require a precise air/fuel ratio signal rather than a universal replacement. The specific-fit design helps maintain proper sensor placement and connector routing, while the heated configuration supports stable operation once installed. This part cross-references DENSO Auto Parts 234-5075 for the same application.

For Mitsubishi Outlander service, this sensor matches the listed upstream left position for 2014-2016 models. The NTK 27025 is engineered with OE-style fit, form, and function, and it is manufactured and tested to meet or exceed original equipment expectations. Use it when replacing a worn or failed air/fuel ratio sensor on the specified application.

What It Is Used For

  • Replacing a failed air/fuel ratio sensor
  • Restoring accurate exhaust mixture feedback
  • Addressing sensor-related fault codes
  • Correcting drivability issues tied to mixture control
  • Maintaining proper emissions system operation

Installation Notes and Tips

Verify the connector, thread size, and harness length before installation. This sensor is a specific-fit part, so confirm the listed application and upstream left position on the vehicle before replacement. The mounting bracket is not included.

Quality Assurance

NTK is a major original equipment oxygen sensor supplier, and this sensor is manufactured and tested to meet or exceed OE specifications for fit and reliability.
