NTK 24310 Air / Fuel Ratio Sensor - Upstream, Upstream Left or Upstream Right

Overview

NTK 24310 is a direct-fit heated air/fuel ratio sensor built for specific import applications. It uses a 5-wire design and OE-equivalent construction to support accurate mixture monitoring in the exhaust stream.

Compatible With Audi Q7, Volkswagen Touareg, Audi A8 Quattro, Volkswagen Golf, Volkswagen Jetta, Volkswagen Passat, and Volkswagen R32 applications listed below. The NTK 24310 is a specific-fit replacement that follows the original sensor layout for the covered vehicles.

Key Features

• Heated air/fuel ratio sensor for faster operating response.
• 5-wire configuration for application-specific signal control.
• Direct-fit design for covered import vehicles.
• OE-equivalent construction for form and function alignment.
• 69.8-inch wiring harness length for listed fitments.
• 18.000 mm thread diameter with 0.38 thread length.

Detailed Description

NTK 24310 is part of the Direct Fit 5-Wire A/F Sensor line, a product family focused on application-specific oxygen and air/fuel ratio sensing. NTK draws on its OE sensor manufacturing background and ceramic technology to produce sensors that match original equipment expectations for fit, form, and function. This part number, 24310, is used across multiple Audi and Volkswagen upstream applications, including Bank 1 Sensor 1 and manifold-mounted locations where specified.

For Audi Q7 and Volkswagen Touareg coverage, this sensor is listed for upstream right and upstream left positions. It is also cataloged for Audi A8 Quattro, Volkswagen Golf, Volkswagen Jetta, Volkswagen Passat, and Volkswagen R32 applications with notes that identify OE-equivalent design and specific bank/sensor locations. If you are replacing a failed sensor on an Audi Q7 or Volkswagen Jetta, 24310 provides a direct-fit path that matches the original configuration called out in the fitment data.

This part cross-references Bosch 17361 and DENSO Auto Parts 234-5045 for the same application.

What It Helps Address

• Check engine lights related to air/fuel ratio sensor faults.
• Incorrect mixture readings from a worn heated sensor.
• Slow sensor response during closed-loop operation.
• Fitment issues caused by using a universal sensor instead of a specific-fit part.
• Replacement needs for upstream sensor locations on covered Audi and Volkswagen models.

Installation Notes and Tips

Verify the exact year, model, and sensor position before ordering. Fitment includes upstream right, upstream left, and upstream applications, with some listings tied to bank and sensor identifiers such as B1S1 or B3S1. The sensor uses a specific-fit configuration, so confirm connector and thread specifications against the original part before installation.

Quality Assurance

NTK states that its oxygen sensors are extensively tested during manufacturing and built to meet or exceed OE specifications. The brand is part of the NGK family and is recognized as a major original equipment sensor manufacturer.
