NTK 24633 Oxygen Sensor - Downstream, Downstream Front or Upstream

Direct-Fit Oxygen Sensor

NTK oxygen sensor 24633 is a specific-fit, heated sensor built for direct replacement applications. It uses a threaded mounting design and a 4-wire configuration with an 18.5-inch harness for a precise service fit.

Key Features

• Heated oxygen sensor for faster operating response.
• Specific-fit design for direct replacement service.
• Threaded mounting with 18 mm thread diameter.
• 4-wire construction for signal and heater circuit operation.
• 18.5-inch wiring harness length.

Detailed Description

NTK 24633 is part of the Direct Fit Oxygen Sensor line, engineered for applications that require an OE-style replacement with the correct connector, harness length, and threaded mounting style. As an oxygen sensor for import and domestic vehicles, it reflects NTK's focus on sensor coverage and application-specific fitment. This part cross-references Bosch 13007 and DENSO Auto Parts 234-4065 for the same application.

Compatible with select Acura NSX, Honda Civic, Honda Civic del Sol, and Acura TL applications, this sensor is listed for downstream and upstream positions depending on the vehicle. For 2000-2005 Acura NSX, it fits the downstream front location; for 1996-2000 Honda Civic, it fits the downstream location; for 1999 Acura TL, it fits the upstream location; and for 1996-1997 Honda Civic del Sol, it fits the downstream location. Use NTK 24633 when replacing a worn sensor that needs OE-equivalent form and function.

What It Is Used For

• Replacing a failed heated oxygen sensor.
• Restoring accurate exhaust oxygen feedback.
• Addressing check engine light concerns tied to sensor performance.
• Correcting drivability issues caused by degraded air-fuel monitoring.
• Replacing a sensor with the wrong harness or mounting style.

Installation Notes and Tips

Verify the vehicle's position, connector style, and thread size before installation. Match the listed fitment exactly, since this is a specific-fit oxygen sensor and not a universal part. Confirm the harness routing and sensor location against the original unit before final installation.

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 and is recognized as a major original equipment oxygen sensor supplier.
