NTK 24619 Oxygen Sensor - Upstream Left or Upstream Right

Direct Fit Oxygen Sensor for OE Replacement

The NTK 24619 direct fit oxygen sensor is a heated, threaded replacement built for specific applications on select Infiniti and Nissan models. It uses a 3-wire design with a 26.75-inch wiring harness and 18 mm thread diameter for OE-style service on upstream right and upstream left positions.

NTK’s Direct Fit Oxygen Sensor line focuses on original-equipment style fit, form, and function. As part of the NGK family, NTK applies ceramic manufacturing expertise and production testing to support consistent sensor performance for import and domestic vehicles.

Key Features

• Heated oxygen sensor for faster operating temperature
• Specific fit design for direct replacement service
• 3-wire configuration with 26.75-inch harness length
• 18 mm threaded mounting type
• OE-style replacement for select Infiniti I30, Infiniti QX4, Nissan Maxima, and Nissan Pathfinder applications
• Part number 24619 for catalog and cross-reference lookup

Detailed Description

NTK 24619 is a direct fit oxygen sensor engineered for select 2000-2001 Infiniti I30, 2001 Infiniti QX4, 2000-2001 Nissan Maxima, and 2001 Nissan Pathfinder applications. It is listed for upstream right and upstream left positions depending on the vehicle, including Bank 1 Sensor 1 and Bank 2 Sensor 1 configurations shown in the fitment data. This part cross-references Bosch 13350 and DENSO Auto Parts 234-3110 for the same application.

Built as a heated, threaded sensor with a specific-fit design, the NTK 24619 supports OE-style replacement where accurate exhaust oxygen feedback is required for engine management. The NTK Direct Fit Oxygen Sensor line is backed by the brand’s long-standing role as a major OE sensor manufacturer and its controlled ceramic production process.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio feedback to the engine control system
• Slow sensor response during closed-loop operation
• Fault codes tied to upstream oxygen sensor circuits
• Emissions test failures caused by a worn sensor

Installation Notes and Tips

Verify the vehicle’s year, engine configuration, and sensor position before ordering. This NTK 24619 sensor is specific to the listed upstream right and upstream left applications, so match the original connector, harness length, and thread size to the existing part. For best results, inspect the exhaust threads and wiring routing before installation on Infiniti I30, Infiniti QX4, Nissan Maxima, or Nissan Pathfinder models.

Quality Assurance

NTK states that its oxygen sensors are manufactured and tested to meet or exceed OE specifications. The brand also emphasizes OE application coverage and production control from raw ceramic material through finished sensor assembly.
