Product Details

NTK is known for oxygen sensor manufacturing across import and domestic applications, and the 24553 reflects that OE-focused approach. As part of the NTK Direct Fit Oxygen Sensor line, this part is engineered for proper fit, form, and function on covered vehicles such as the Toyota 4Runner, Toyota Tacoma, and Lexus LX450. The sensor is extensively tested during manufacturing to help meet or exceed OE specifications, and NTK’s ceramic manufacturing expertise supports consistent sensor construction from raw material through finished product. This part cross-references Bosch 13095 and DENSO Auto Parts 234-4153 for the same application.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings
• Slow or inaccurate sensor response
• Emissions test failures tied to a faulty upstream or downstream sensor
• Rough running caused by degraded exhaust feedback data

Installation Notes and Tips

Verify the sensor position before ordering, since this part is listed for both upstream and downstream locations depending on vehicle application. Confirm the thread diameter, flange mounting style, wire count, and harness length against the original sensor before installation. For covered applications, use the vehicle’s emissions configuration and model year to match the correct Toyota 4Runner, Tacoma, Land Cruiser, Previa, T100, or Lexus LX450 application.

Quality Assurance

NTK manufactures oxygen sensors to OE-level specifications and tests them during production for quality and reliability. The brand’s OE application focus and sensor specialization support consistent replacement performance for select Toyota and Lexus emissions systems.
