This part cross-references OE-style applications for the same vehicle coverage, including 3921023950 and 3921023750.

What It Is Used For

• Replacing a failed oxygen sensor that triggers a check engine light
• Restoring exhaust feedback for fuel control on Hyundai Elantra and Accent models
• Addressing sensor faults on Kia Rio, Rio5, Soul, Sportage, Spectra, and Spectra5
• Correcting upstream or downstream sensor readings on supported applications
• Matching OE-numbered emissions service parts for listed vehicles

Installation Notes and Tips

Verify the sensor position before ordering, since fitment includes upstream, upstream rear, and downstream locations. Match the OE number in the notes to the vehicle application, and confirm connector and sensor placement against the original part before installation. For best results, inspect the exhaust threads and wiring routing during replacement.

Quality Assurance

Hella and the Pierburg distributed by Hella line provide OE-referenced coverage for the listed Hyundai and Kia applications. Confirm fitment by year, make, model, position, and OE number before installation.
