NTK 24574 Oxygen Sensor - Downstream Right

Direct Fit Oxygen Sensor for Nissan and Infiniti

NTK 24574 is a direct fit heated oxygen sensor built for specific downstream right applications on select Nissan and Infiniti vehicles. It uses an OE-equivalent threaded design with a 4-wire configuration and a 39.5-inch wiring harness for a factory-style replacement.

Key Features

• Direct fit oxygen sensor for specific applications
• Heated sensor design for faster operating response
• 4-wire construction
• 39.5-inch wiring harness length
• 18 mm thread diameter with threaded mounting
• OE-equivalent fit, form, and function

Product Line Details

NTK Direct Fit Oxygen Sensor parts are part of the brand’s OE-focused sensor line. NTK applies ceramic manufacturing expertise and production controls from raw material through finished sensor, supporting consistent construction for import and domestic emission control applications. Part number 24574 follows that direct replacement approach for downstream right locations on select Infiniti I30, Infiniti QX4, Nissan Maxima, and Nissan Pathfinder models.

Fitment

• Fits 2000-2001 Infiniti I30, downstream right.
• Fits 2001 Infiniti QX4, downstream right. B1S2; 2001 model year; to 8/1/00.
• Fits 2001 Nissan Maxima, downstream right.
• Fits 2001 Nissan Pathfinder, downstream right. B1S2; 2001 model year; to 8/1/00.
• Fits 1999-2000 Nissan Maxima, downstream right. B1S2 California emissions OE equivalent design.
• Fits 1999 Infiniti I30, downstream right. B1S2 California emissions OE equivalent design.
• Fits 1998 Nissan Maxima, downstream right. B1S2; from 6/98; California emissions; OE equivalent design.

Common Uses

• Replacing a failed downstream oxygen sensor
• Addressing check engine light concerns related to oxygen sensor performance
• Restoring proper exhaust feedback for emission control monitoring
• Correcting drivability issues tied to inaccurate sensor readings
• Replacing a damaged or aging factory-style sensor on compatible Nissan and Infiniti applications

Installation Notes

Verify the downstream right location, connector routing, and model-year notes before installation. The threaded mounting and specific-fit design are intended for direct replacement on the listed applications, and the 4-wire heated sensor should be matched to the original configuration. This part cross-references Bosch (e.g., 13374, 15377) for the same application.

Quality Assurance

NTK manufactures oxygen sensors to meet or exceed OE specifications and tests them during production for quality and reliability. As the sensor specialist within the NGK family, NTK supports OE application coverage for import and domestic emission control systems.
