Direct Fit Air/Fuel Ratio Sensor

NTK 24347 is a specific-fit heated air/fuel ratio sensor for select Porsche, Volkswagen, and Audi applications. It is built as a direct-fit 5-wire sensor with OE-style form and function for accurate replacement service.

Key Features

  • Direct-fit 5-wire air/fuel ratio sensor for specific applications
  • Heated sensor design for faster operating readiness
  • 68.0 wiring harness length for application-specific routing
  • 18.000 thread diameter with 0.38 thread length
  • Mounting bracket not included

Detailed Description

NTK 24347 is engineered for select upstream oxygen sensor locations across Porsche Cayenne, Porsche Panamera, Volkswagen Touareg, Volkswagen Beetle, Audi A8 Quattro, Audi S8, and Volkswagen Phaeton applications. The sensor uses a 5-wire heated design and is listed as a specific-fit replacement, which helps maintain the original sensor configuration and connector style for the vehicle platform. NTK 24347 is part of the Direct Fit 5-Wire A/F Sensor line, a product line focused on application-specific replacement coverage. This part cross-references Bosch 17182 and DENSO Auto Parts 234-5119 for the same application.

Common Uses

  • Replaces a worn or slow-responding air/fuel ratio sensor
  • Addresses sensor fault codes related to mixture control
  • Restores proper upstream exhaust feedback for engine management
  • Helps correct drivability issues tied to inaccurate oxygen sensing
  • Supports replacement service on select Porsche Cayenne and Volkswagen Touareg applications

Installation Notes and Tips

Verify the exact year, model, engine configuration, and sensor position before ordering. Fitment includes upstream left and upstream locations, with notes that vary by chassis, cylinder bank, and manifold placement on some applications. Use the listed thread size and harness length to confirm routing and mounting clearance during installation.

Quality Assurance

NTK is part of the NGK family of products and is a major original equipment oxygen sensor manufacturer. This sensor is manufactured and tested to meet or exceed OE specifications for fit, form, and function.
