Detailed Description

NTK 24131 is part of the Direct Fit Oxygen Sensor line and is engineered for import and domestic coverage with OE application technology. NTK draws on its role as a major original equipment oxygen sensor supplier and uses controlled ceramic manufacturing processes to support fit, form, and function. This oxygen sensor is built to meet or exceed OE specifications through manufacturing tests that focus on quality and reliability. It fits 2021-2024 Lexus IS300, downstream left; 2021-2024 Lexus IS350, downstream left; 2021-2024 Lexus RC300, downstream left; 2021-2024 Lexus RC350, downstream left; 2016-2020 Lexus GS350, downstream left; 2016-2020 Lexus GS350, downstream right; 2018-2020 Lexus IS300, downstream left; 2018-2020 Lexus IS300, downstream right; 2018-2020 Lexus IS350, downstream left; 2018-2020 Lexus IS350, downstream right; 2018-2020 Lexus RC300, downstream left; 2018-2020 Lexus RC300, downstream right; 2018-2020 Lexus RC350, downstream left; 2018-2020 Lexus RC350, downstream right; 2006 Lexus GS300, downstream left; and 2006 Lexus GS300, downstream right. This part cross-references Bosch 15119 and DENSO Auto Parts 234-4806 for the same application.

What It Is Used For

  • Replacing a failed downstream oxygen sensor
  • Restoring proper exhaust gas feedback to the engine control system
  • Addressing check engine light conditions related to oxygen sensor performance
  • Correcting drivability issues caused by inaccurate air-fuel monitoring

Installation Notes and Tips

Verify the connector style, harness length, thread diameter, and downstream left or right position before installation. Use the vehicle-specific fitment listing to confirm the exact Lexus application for the 24131 oxygen sensor. Threaded sensors should be installed with care to avoid cross-threading and to ensure proper sealing.

Quality Assurance

NTK tests these oxygen sensors during manufacturing to support quality and reliability that meet or exceed OE specifications. The 24131 is backed by NTK's OE-focused engineering and application coverage.
