Description
Additional information

The NTK Wideband sensor is a lab grade wide band air fuel ratio sensor that we specify for any alcohol based application. Typical alcohol applications are boosted combinations and you need a sensor that’s built rugged enough to stand the harshest conditions while reading down to extremely low air fuel ratios.

With this sensor you can feel confident knowing that you are getting the most accurate air fuel ratio sensor on the market and one that will last for years to come. We can configure your ECU so that you can run two of these for any type of dual exhaust applications. Using the GEN4 ECU this sensor can be calibrated to ensure the sensor is working properly and reading within the appropriate ranges. 

We do not recommend these in the turbo exhaust crossover sections as these are not pressure compensated.
