Direct-Fit Downstream Oxygen Sensor

NTK 25744 is a specific-fit, heated oxygen sensor built for downstream applications with an OE-equivalent design. It is engineered for import applications and uses a threaded mounting style for direct replacement service.

Key Features

  • Heated oxygen sensor for downstream exhaust monitoring
  • Specific-fit design for direct replacement service
  • 4-wire configuration with a 27.5-inch harness length
  • 18 mm thread diameter and threaded mounting type
  • NTK 25744 is part of the Direct Fit Oxygen Sensor line

Detailed Description

NTK 25744 is a downstream oxygen sensor for select BMW and Mini applications, including the Mini Cooper, Mini Cooper Clubman, Mini Cooper Countryman, BMW X1, BMW X2, and BMW i8. The direct-fit design supports OE-style replacement without universal adaptation, and the heated sensor construction helps maintain signal performance as exhaust temperatures change. As part of NTK's Direct Fit Oxygen Sensor line, this part is built around application-specific coverage and OE-equivalent form and function. This part cross-references BMW 11788604889 and 11788617030 for the same application.

What It Is Used For

  • Replacing a worn downstream oxygen sensor
  • Addressing check engine light concerns related to oxygen sensor performance
  • Restoring exhaust feedback for fuel control and emissions monitoring
  • Correcting drivability issues caused by inaccurate sensor readings
  • Replacing a sensor with damaged wiring or threaded mounting wear

Installation Notes and Tips

Verify the downstream location, connector style, thread diameter, and harness length before installation. Confirm the vehicle application against the fitment list for the exact BMW or Mini model and year. Use the threaded mounting point and specific-fit configuration to match the original sensor layout.

Quality Assurance

NTK states that its oxygen sensors are extensively tested during manufacturing and are built to meet or exceed OE specifications. The brand is part of the NGK family and is recognized as a major original equipment oxygen sensor supplier.
