Fitment and Application
Fits 2015-2020 Ford Mustang, upstream right. This NTK 27031 air/fuel ratio sensor is listed for OE manufacturer application coverage and is intended for vehicles that require the specified sensor configuration. For buyers searching for a Ford Mustang upstream right air/fuel ratio sensor, the NTK 27031 provides a direct-fit option with the correct wire count and threaded mounting dimensions.
NTK’s Direct Fit 5-Wire A/F Sensor line focuses on application-specific replacement parts rather than universal coverage. That makes it a practical choice when you need the correct connector style, harness length, and sensor type without adapting the wiring or mounting point.

Common Replacement Issues
- Fault codes related to air/fuel ratio sensor performance
- Rough idle or inconsistent fuel control from a failing sensor
- Delayed sensor response affecting engine management
- Need for a direct-fit replacement with OE-style dimensions
Installation Notes
Verify the connector, thread diameter, and harness length before installation. This sensor uses a specific-fit design, so matching the vehicle application and upstream right position is important. Confirm the existing sensor configuration against the vehicle service information before replacement.
