When putting in a 02 in a exhaust. How deep should the sensor go in the pipe? I think i read at some time to do it flush.

This is for air/fuel.

If the bung is welded in properly the vented dome should sit in the center of the pipe when installed.

How deep should the sensor go in the pipe? If you put it all the way in. It will make the exhaust flow bad and burn sensor out. I would think.

The tip of the sensor should be at the center of the pipe and at a 10-15 Deg. angle to the horizontal. If not... any liquid contacting the sensor(usually at cold start up) will cause thermal shock and kill the sensor.Also placing it too close to the header will cause it to fail,from too high of heat. Placing it in this position will not adversly affect the flow in the pipe.
