Direct-Fit Air/Fuel Ratio Sensor
NTK 24791 is a specific-fit, heated air/fuel ratio sensor built for import applications that require OE-style signal control and direct-fit installation. It is part of NTK’s Direct Fit 4-Wire A/F Sensor line and is engineered for accurate replacement on select Nissan and INFINITI models.
- Specific-fit replacement for select applications
- Heated sensor design for faster operating response
- 4-wire configuration for OE-style electrical connection
- 14.7500 wiring harness length for application-specific routing
- 18.000 thread diameter with 0.38 thread length
Fitment and Application Details
Compatible with 2013-2018 Nissan Altima, upstream, including B1S1 California emissions applications. Fits 2011-2017 Nissan Juke, upstream. Fits 2012-2017 Nissan NV2500, upstream right and upstream left. Fits 2012-2017 Nissan NV3500, upstream right and upstream left. Fits 2011-2012 INFINITI G25, upstream right and upstream left. NTK 24791 is a direct-fit air/fuel ratio sensor for vehicles that use an OE-equivalent sensor layout.
What It Helps Address
- Faulty air/fuel ratio sensor readings
- Check engine light concerns related to sensor performance
- Rough fuel control caused by a worn heated sensor
- OE-style replacement needs for specific Nissan and INFINITI applications
Installation Notes and Tips
Use the vehicle’s exact year, engine, emissions package, and sensor position to confirm application before installation. This sensor uses a specific-fit design and a 4-wire configuration, so connector and routing match-up should be verified against the original part. The mounting bracket is not included.
