NTK 24688 Oxygen Sensor - Downstream

Direct Fit Oxygen Sensor

NTK 24688 is a specific-fit heated oxygen sensor built for downstream applications with a threaded mounting design. It is engineered for direct replacement use and matches the original equipment style expected for emission control service.

Compatible with Mitsubishi Lancer and Mitsubishi Outlander applications, this NTK oxygen sensor uses a 4-wire layout and a 21.7500 wiring harness length. The 18.000 thread diameter and threaded mounting type support a precise installation on the intended exhaust location.

Key Features

• Heated oxygen sensor for downstream emission control service
• Specific-fit design for direct replacement applications
• 4-wire configuration for signal and heater circuit operation
• Threaded mounting type for secure installation
• 21.7500 wiring harness length for the intended routing

Detailed Description

NTK 24688 is part of the Direct Fit Oxygen Sensor line, which focuses on application-specific replacement parts rather than universal coverage. NTK combines ceramic sensor manufacturing expertise with OE-oriented engineering to deliver fit, form, and function that align with original equipment requirements. This part cross-references DENSO Auto Parts (e.g., 234-4281, 234-4282) for the same application.

Fits 2004-2006 Mitsubishi Lancer, downstream. Fits 2004-2006 Mitsubishi Outlander, downstream. For Mitsubishi Lancer and Mitsubishi Outlander service, this oxygen sensor is a direct-fit option for the downstream location and is built to match the specified threaded installation.

What It Is Used For

• Replacing a worn or slow-responding downstream oxygen sensor
• Restoring proper exhaust gas feedback to the engine control system
• Addressing sensor-related fault codes tied to mixture control
• Correcting emissions inspection issues caused by sensor degradation
• Replacing a damaged threaded sensor with the correct fitment

Installation Notes and Tips

Verify the downstream location, thread diameter, and harness length before installation. Confirm the connector routing and wire count match the original sensor on the vehicle. Use the listed fitment for 2004-2006 Mitsubishi Lancer and 2004-2006 Mitsubishi Outlander applications only.

Quality Assurance

NTK states that its oxygen sensors are extensively tested during manufacturing and are built to meet or exceed OE specifications. As part of the NGK family of products, NTK supports import and domestic applications with OE application technology and broad coverage.
