• 4-wire configuration for signal and heater circuit operation
• Threaded mounting type for secure installation
• 24.5-inch wiring harness length
• 18 mm thread diameter

Detailed Description

NTK 24650 is part of the Direct Fit Oxygen Sensor line from NTK, a brand known for OE-focused sensor coverage and ceramic sensor manufacturing expertise. As an oxygen sensor for emission control systems, it is engineered to deliver the fit, form, and function expected in replacement service. This part cross-references Bosch 13785 and DENSO Auto Parts 234-4362 for the same application.

Fits 2003-2006 Mitsubishi Outlander, upstream. For Mitsubishi Outlander models in this range, NTK 24650 provides a direct-fit replacement path for the upstream oxygen sensor location.

What It Is Used For

• Replacing a failed upstream oxygen sensor
• Restoring proper air-fuel ratio feedback
• Addressing sensor heater circuit faults
• Correcting emission control warning conditions

Installation Notes and Tips

Verify the threaded mounting style, wire count, harness length, and upstream location before installation. Confirm the vehicle application against the existing sensor connector and thread size to ensure the correct replacement.

Quality Assurance

NTK tests oxygen sensors during manufacturing to meet or exceed OE specifications. The brand is part of the NGK family of products and supplies original equipment oxygen sensors globally.
