NTK 23099 Oxygen Sensor

Direct Fit Oxygen Sensor for OE Replacement

The NTK 23099 direct fit oxygen sensor is a heated, specific-fit replacement built for import and domestic emission control applications. It is engineered for vehicles that need accurate exhaust feedback, including Dodge Ram, Dodge Dakota, and Jeep Cherokee applications listed below.

• Specific-fit oxygen sensor for direct replacement use
• Heated sensor design for faster operating response
• 4-wire configuration with 18-inch wiring harness length
• Threaded mounting with 18 mm thread diameter
• OE-style fit, form, and function for listed applications

NTK Direct Fit Line Details

NTK’s Direct Fit Oxygen Sensor line is built around original equipment application coverage and streamlined part selection. As part of the NGK family of products, NTK uses ceramic manufacturing expertise and controlled production processes to deliver sensors that match the required physical and electrical characteristics for the vehicle platform. Part number 23099 follows that approach for direct replacement service.

What This Sensor Helps Address

• Check engine light concerns related to oxygen sensor performance
• Incorrect air-fuel feedback affecting drivability
• Slow sensor response during closed-loop operation
• Failed emissions testing tied to a worn downstream or upstream sensor
• Replacement needs for a damaged or aging OE-style sensor

Installation Notes and Tips

Confirm the connector style, sensor position, and emissions calibration before installation. This NTK 23099 oxygen sensor uses a threaded mounting design and a 4-wire heated configuration, so matching the original routing and connector layout is important for proper service on Dodge Ram, Jeep Cherokee, and related applications. This part cross-references Bosch 13138 and DENSO Auto Parts 234-4078 for the same application.

Quality Assurance

NTK manufactures oxygen sensors to meet or exceed OE specifications and tests them during production for quality and reliability. The brand’s OE supplier background and ceramic manufacturing control support consistent fit and function for listed vehicles.
