Key Features

• Direct Fit Oxygen Sensor for specific applications
• Heated sensor design for faster operating readiness
• 4-wire configuration
• 18 mm thread diameter with threaded mounting type
• 14.7500-inch wiring harness length
• OE-style fit, form, and function for emission control service

Product Details

NTK, part number 24588, is part of the Direct Fit Oxygen Sensor line from the Sensor Specialist brand family. NTK applies ceramic manufacturing expertise and OE application coverage to produce oxygen sensors that match original equipment dimensions and electrical requirements. This sensor is extensively tested during manufacturing to support consistent signal performance and reliable operation in emission control systems. It is a direct replacement for downstream and upstream applications listed for Hyundai Elantra, Accent, Tucson, Tiburon, and Kia Rio, Rio5, Soul, Sportage, Spectra, and Spectra5.

This part cross-references Bosch 13461 and DENSO Auto Parts 234-4851 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings on upstream applications
• Slow or inaccurate downstream sensor response
• Emission control faults tied to sensor signal degradation
• Replacement needs after sensor aging or contamination

Installation Notes and Tips

Verify the sensor position before ordering: this part is listed for both upstream and downstream locations depending on vehicle application. Confirm the thread diameter, wire count, and harness length against the original sensor before installation. For best results, compare the connector and routing path to the removed unit on the Hyundai Elantra, Accent, Tucson, Tiburon, or Kia Rio, Rio5, Soul, Sportage, Spectra, or Spectra5.
