Direct Fit Oxygen Sensor for Porsche and Volvo

NTK 25580 is a specific-fit heated oxygen sensor built for direct replacement applications. It uses a threaded mounting design, a 4-wire layout, and a 35-inch harness length to match the original sensor configuration on select Porsche 911 and Volvo models.

Key Features

• Specific-fit oxygen sensor for direct replacement service
• Heated sensor design for faster operating response
• 4-wire construction with a 35-inch wiring harness
• Threaded mounting with an 18 mm thread diameter
• OE-style fit, form, and function from NTK 25580

Detailed Description

NTK 25580 is part of the Direct Fit Oxygen Sensor line, engineered for applications that require an exact-match replacement rather than a universal sensor. NTK uses ceramic-based sensor technology and extensive manufacturing tests to deliver consistent output and OE-level dimensional accuracy. This oxygen sensor is a practical choice for maintaining proper air-fuel feedback on compatible Porsche 911 and Volvo C70, S70, and V70 applications.

NTK is known for original equipment oxygen sensor production, and the 25580 reflects that OE-focused approach with a threaded, heated design and application-specific harness length. For buyers searching for an oxygen sensor for Porsche 911 or a direct fit oxygen sensor for Volvo C70, S70, or V70, this part number provides a targeted replacement path.

What It Is Used For

• Replacing a worn or slow-responding oxygen sensor
• Restoring accurate exhaust oxygen feedback to the engine control system
• Addressing sensor fault codes related to mixture control
• Correcting drivability issues tied to aging emissions sensors
• Maintaining emissions system performance on compatible vehicles

Installation Notes and Tips

Verify the sensor position, connector routing, thread size, and harness length before installation. This NTK oxygen sensor is a specific-fit part, so matching the original application details is important. Confirm fitment for the exact Porsche 911 or Volvo model and sensor location listed for NTK 25580.

Quality Assurance
