Direct-Fit Oxygen Sensor

NTK oxygen sensor 24533 is a specific-fit, heated sensor built for upstream air/fuel ratio control. It uses a threaded mounting design with a 4-wire configuration and a 29.75-inch harness for applications that require an OE-style replacement.

Key Features

• Heated oxygen sensor for faster signal response.
• Specific-fit design for direct replacement applications.
• Threaded mounting with 18 mm thread diameter.
• 4-wire construction with 29.75-inch wiring harness.
• NTK 24533 is part of the Direct Fit Oxygen Sensor line.

Detailed Description

NTK 24533 is an upstream oxygen sensor engineered for precise air/fuel ratio feedback in compatible import applications. It is listed for 1989-1994 Eagle Talon, 1989-1994 Mitsubishi Eclipse, 1989-1994 Plymouth Laser, and related Mitsubishi, Dodge, Eagle, and Plymouth models shown in the fitment data. This part cross-references Bosch 12053 and DENSO Auto Parts 234-4643 for the same application. As an OE-focused sensor specialist, NTK manufactures oxygen sensors with extensive testing and OE-specification targets for fit, form, and function.

What It Is Used For

• Replacing a worn upstream oxygen sensor.
• Restoring accurate air/fuel ratio feedback.
• Addressing sensor-related check engine light concerns.
• Correcting slow or inconsistent sensor response.
• Replacing a damaged threaded sensor or harness connection.

Installation Notes and Tips

Verify the vehicle’s bank and sensor location before ordering. Confirm the threaded mounting style, 18 mm thread diameter, 4-wire layout, and harness length against the original part. Use the fitment notes to match Bank 1 Sensor 1 and DOHC-specific applications where listed.

Quality Assurance

NTK states that these oxygen sensors are extensively tested during manufacturing to meet or exceed OE specifications. The brand is part of the NGK family of products and is recognized as a major original equipment oxygen sensor supplier.
