Denso OE Style Oxygen Sensor 234-4875

Denso 234-4875 is an OE Style heated oxygen sensor built for precise replacement and consistent signal performance. It is a specific-fit sensor for downstream applications on select BMW and Rolls-Royce models, including BMW X5, BMW X6, BMW M3, and Rolls-Royce Phantom.

The OE Style line is engineered to match original equipment fit and function, with a first-time fit approach that helps simplify replacement on downstream oxygen sensor locations. Denso also uses an aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting stable engine management and fuel control.

  • Heated oxygen sensor for downstream exhaust monitoring
  • Specific-fit design with threaded mounting
  • 4-wire configuration with female connector
  • Wiring harness length: 12.20
  • Thread diameter: 0.708
  • OE Style replacement for direct-fit service

What This Sensor Helps Address

  • Check engine light related to oxygen sensor performance
  • Incorrect air-fuel ratio feedback from a worn downstream sensor
  • Reduced fuel economy caused by inaccurate exhaust readings
  • Slow or unstable sensor response during closed-loop operation
  • Exhaust monitoring faults on BMW and Rolls-Royce applications

Installation Notes and Tips

Confirm the downstream location, connector style, wire count, and thread diameter before installation. This sensor is a specific-fit replacement for threaded mounting applications, so matching the original harness length and connector gender is important for proper routing and connection. For BMW X5, BMW M3, BMW X6, and Rolls-Royce Phantom applications, verify the exact position shown in the fitment list before ordering.

This part cross-references Bosch 16421 and NTK 25612 for the same application.

Quality Assurance

Denso manufactures and tests these oxygen sensors to OE standards for accurate replacement fitment and dependable operation. The OE Style design focuses on original-equipment dimensions and signal performance, and the protective trap layer is used to help preserve the sensing element from contamination that can shorten service life.
