Where do I put the Wideband?
Most WBo2 sensors come with a stainless steel exhaust bung for the sensor to thread into. These wideband do come with a bung for you. This bung should be welded as close to the front of the exhaust stream as possible, and before any catalytic converters. For the sensor's accuracy, it's crucial that you do not have any exhaust leaks up-stream of the sensor. If you are turbocharged, it's also important to know that these consumer grade sensors are not intended to be installed before the turbo, as the exhaust back pressure will affect the readings, and the extreme heat will quickly burn up the sensor.
Do these replace narrow-band o2 sensors? Nope. Your car relies on its narrow-band o2 sensors for closed loop operation, and without your narrow-band sensors, you will not be able to learn fuel trims. Factory ECUs aren't able to understand the output of a WBo2, and would not be able to take advantage of the wealth of data provided by them.There are some WBo2s (Innovate, for instance), that can emulate a narrow-band o2 sensor and take their place. I personally would recommend the simplicity of running both the factory narrow-band sensors, and an on-board WBo2..
