Direct-Fit Air/Fuel Ratio Sensor

NTK 27055 is a direct-fit heated air/fuel ratio sensor for specific import applications. It is built for upstream use and follows OE-equivalent design requirements for accurate signal response and proper system operation.

Compatible with Volkswagen Atlas, Volkswagen Tiguan, Audi A3, and Audi S3 applications listed below, this NTK sensor is part of the Direct Fit 5-Wire A/F Sensor line. The 5-wire heated design supports faster sensor warm-up, while the specific-fit construction helps simplify replacement on the correct application.

Key Features

  • Direct-fit replacement for specific upstream air/fuel ratio sensor applications
  • Heated sensor design for quicker operating temperature
  • 5-wire configuration for the listed OE-equivalent applications
  • Specific-fit design for accurate installation on supported vehicles
  • NTK engineering backed by OE sensor manufacturing experience

Detailed Application Overview

Part number 27055 is engineered for upstream air/fuel ratio monitoring on a range of Volkswagen and Audi models, including Volkswagen Atlas, Volkswagen Tiguan, Audi A3, Audi A3 Quattro, Audi A8 Quattro, Audi RS7, Audi S3, Audi S6, Audi S7, Audi S8, Audi TT Quattro, Audi TTS Quattro, Volkswagen Golf R, and Volkswagen GTI. Fitment includes Bank 1 Sensor 1 and other OE-equivalent upstream applications as listed in the fitment table, so the correct year, model, and notes should be verified before ordering. NTK 27055 is designed to match the original sensor style and connection requirements for the specified vehicles.

NTK is known for oxygen sensor manufacturing and uses ceramic technology developed in-house to control sensor materials from raw input through finished product. This product line is tested during manufacturing to meet or exceed OE specifications for fit, form, and function. Part number 27055 is a direct-fit option for buyers replacing an upstream air/fuel ratio sensor on supported Volkswagen and Audi platforms.

What It Helps Address

  • Fault codes related to upstream air/fuel ratio sensor performance
  • Incorrect fuel trim readings from a worn sensor
  • Slow sensor response during closed-loop operation
  • Driveability issues tied to inaccurate exhaust oxygen feedback
  • Replacement needs for OE-equivalent sensor service on supported vehicles

Installation Notes and Quality

Verify the vehicle year, model, engine configuration, and fitment notes before installation, especially where Bank 1 Sensor 1 or date-specific notes are listed. The sensor uses a 5-wire heated design and a specific-fit configuration, so matching the connector and application details is important for proper installation.

NTK states that its oxygen sensors are extensively tested during manufacturing to meet or exceed OE specifications. Part number 27055 reflects that OE-focused approach for supported Volkswagen and Audi applications.
