NTK 23525 Oxygen Sensor - Downstream

Direct-fit oxygen sensor

NTK oxygen sensor 23525 is a specific-fit, heated sensor built for downstream applications. It uses a threaded mounting design with a 4-wire configuration and a 21.75-inch harness for a direct replacement setup.

Key features

• Specific-fit oxygen sensor for targeted application coverage
• Heated sensor design for faster operating response
• Threaded mounting type for secure installation
• 4-wire construction with 21.75-inch wiring harness
• 18 mm thread diameter

Detailed description

NTK 23525 is part of the Direct Fit Oxygen Sensor line, engineered for import and domestic applications with OE-style fit, form, and function. NTK draws on its background as a major original equipment oxygen sensor supplier, and this sensor is manufactured and tested to meet or exceed OE specifications. Compatible With 2001-2005 Chrysler Sebring, downstream; 2001-2005 Dodge Stratus, downstream; 2001-2005 Mitsubishi Eclipse, downstream; and 2001-2003 Mitsubishi Galant, downstream. It also covers 2000 Mitsubishi Eclipse, downstream, and 1999-2000 Mitsubishi Galant, downstream, including California emissions OE-equivalent downstream applications. This part cross-references Delphi ES20085 and DENSO Auto Parts 234-4652 for the same application. Part number 23525 is a practical choice when replacing a worn downstream oxygen sensor in Chrysler Sebring, Dodge Stratus, or Mitsubishi Eclipse applications.

What it is used for

• Replacing a failed downstream oxygen sensor
• Restoring accurate exhaust oxygen feedback
• Addressing check engine light concerns tied to sensor performance
• Correcting drivability issues related to aging sensor response
• Supporting emissions system operation on covered applications

Installation notes and tips

Verify the downstream location, thread diameter, wire count, and harness length before installation. Confirm the vehicle’s emissions configuration, especially on California emissions applications, and compare the connector and routing to the original sensor. Use the part number 23525 to match the correct direct-fit replacement for the listed applications.

Quality assurance

NTK tests these oxygen sensors during manufacturing to help ensure quality and reliability that meet or exceed OE specifications. The brand’s OE-supplier background and direct-fit product line support consistent replacement performance.
