Direct Fit Oxygen Sensor for Import Applications

NTK oxygen sensor 24031 is a direct fit, heated sensor built for specific downstream applications. It uses a threaded mounting design and a 4-wire configuration with a 24.5-inch harness for a precise replacement on supported vehicles.

Key Features

• Direct fit oxygen sensor for specific applications
• Heated design for faster sensor operation
• 4-wire configuration with 24.5-inch harness
• Threaded mounting with 18 mm thread diameter
• NTK part number 24031

Detailed Description

NTK 24031 is part of the Direct Fit Oxygen Sensor line, engineered for exact replacement use where the original sensor is specified by the vehicle application. As an NTK oxygen sensor, it reflects the brand’s focus on OE-style fit, form, and function, with manufacturing controls that cover the ceramic element from raw material through finished product. This part number 24031 is listed for downstream locations on select Eagle Summit, Mitsubishi Mirage, Dodge Colt, and Plymouth Colt applications, including Federal and California emissions configurations. For buyers searching for an oxygen sensor for a Mitsubishi Mirage, Eagle Summit oxygen sensor replacement, or a Dodge Colt downstream sensor, NTK 24031 provides a specific-fit solution.

What It Is Used For

• Replacing a worn or slow-responding downstream oxygen sensor
• Addressing check engine light concerns tied to sensor performance
• Restoring proper exhaust feedback for emissions control
• Correcting drivability issues related to inaccurate air-fuel readings
• Replacing a damaged threaded sensor with the correct harness length

Installation Notes and Tips

Verify the vehicle’s emissions configuration, model year, and downstream sensor location before ordering. Confirm the 18 mm thread diameter, 4-wire layout, and harness length match the original part. This sensor is listed for specific fitment only, so compare the connector and mounting style to the existing unit before installation.

Quality Assurance

NTK states that its oxygen sensors are extensively tested during manufacturing 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.
