Direct-Fit Oxygen Sensor

NTK 24427 is a direct-fit heated oxygen sensor built for specific applications and threaded mounting. It is engineered for accurate exhaust monitoring and OE-style fit, form, and function. Compatible with 2001 Honda Insight downstream applications, this sensor supports precise replacement needs for the Honda Insight.

Key Features

• Heated oxygen sensor design for faster operating readiness.
• Specific-fit application for straightforward replacement.
• Threaded mounting type for secure installation.
• 4-wire configuration with a 10.2500 wiring harness length.
• 18.000 thread diameter for the listed application.

Detailed Description

The NTK Direct Fit Oxygen Sensor line is built around OE application coverage and streamlined replacement fitment. NTK 24427 uses a heated sensing element and a threaded mount to match the listed application requirements, helping maintain proper exhaust feedback for engine management systems. For 2001 Honda Insight downstream service, this oxygen sensor is a direct-fit replacement that aligns with the original configuration.

NTK is part of the NGK family of products and is recognized as a major original equipment oxygen sensor supplier. That background is reflected in the sensor's OE-focused design and manufacturing approach. This part cross-references DENSO Auto Parts 234-4620 for the same application.

What It Is Used For

• Replacing a failed downstream oxygen sensor.
• Restoring exhaust gas feedback to the engine control system.
• Addressing check engine light concerns related to oxygen sensor performance.
• Correcting drivability issues tied to inaccurate air-fuel monitoring.

Installation Notes and Tips

Verify the connector style, thread size, and harness length against the original sensor before installation. Use the listed downstream application only, and confirm the sensor location matches the vehicle's service information. Threaded oxygen sensors should be removed and installed with care to avoid damage to the exhaust bung or sensor body.

Quality Assurance

NTK states that these oxygen sensors are extensively tested during manufacturing to meet or exceed OE specifications. The brand's OE-supplier background and application-specific design support consistent replacement quality for the listed fitment.
