NTK 24593 Oxygen Sensor - Downstream

Direct Fit Oxygen Sensor Overview

NTK 24593 is a direct fit heated oxygen sensor built for specific applications and engineered for OE-style fit, form, and function. It is a threaded sensor with a 4-wire design and a 13-inch harness length for a precise replacement on supported Hyundai Accent applications.

Compatible with Hyundai Accent downstream oxygen sensor applications, this NTK oxygen sensor is part of the Direct Fit Oxygen Sensor line. The design focuses on streamlined coverage and application-specific replacement, making it a practical choice for emissions repair work.

Key Features

• Heated oxygen sensor design for specific-fit replacement
• 4-wire configuration for supported emissions systems
• 13-inch wiring harness length
• Threaded mounting type with 18 mm thread diameter
• OE-style fit, form, and function

Detailed Description

NTK 24593 is engineered for downstream use on select Hyundai Accent models. The sensor is built with a specific-fit design and threaded mounting to match the original application, helping maintain proper exhaust feedback for the engine management system. NTK’s oxygen sensor program is backed by extensive manufacturing testing and OE-focused engineering, with the brand drawing on its role as a major original equipment oxygen sensor supplier. This part cross-references Bosch 13394 and DENSO Auto Parts 234-4693 for the same application.

Fits 1998-1999 Hyundai Accent, downstream. Fits 1997 Hyundai Accent, downstream.

What It Is Used For

• Replacing a worn or slow-responding downstream oxygen sensor
• Addressing emissions-related fault codes tied to sensor performance
• Restoring proper exhaust gas feedback to the engine control system
• Correcting drivability issues caused by inaccurate air-fuel monitoring

Installation Notes and Tips

Verify the connector, harness length, thread diameter, and downstream location before installation. Confirm the vehicle build date for 1997 Hyundai Accent applications, since one fitment row notes production from 5/1/97. Use the exact application listing to match the sensor to the correct exhaust position.

Quality Assurance

NTK tests oxygen sensors during manufacturing to help ensure quality and reliability that meet or exceed OE specifications. The brand is part of the NGK family of products and is recognized for OE oxygen sensor manufacturing expertise.
