This part cross-references Bosch (e.g., 16140, 16323) for the same application.
What it helps address
- Faulty oxygen sensor readings that trigger emissions-related warning lights.
- Slow sensor response that can affect fuel control feedback.
- Downstream sensor replacement needs on supported Porsche applications.
- Fitment issues caused by using a universal sensor instead of a specific-fit part.
Installation notes and quality
Use the listed fitment data to confirm the correct downstream position before installation. The threaded design supports direct-fit replacement on the specified Porsche applications. NTK states that these oxygen sensors are extensively tested during manufacturing and built to meet or exceed OE specifications.
This part fits 67 vehicles
Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
