Ive seen bungs with a 90 deg built in, im assuming to keep the sensor out of the direct exhaust stream. Does anyone know why would you keep the sensor out of the stream?

I cannot answer your question per se, but when I looked for bungs, I ended up going to the local nut/ bolt store here and bought an 18mm nut for I think less a dollar apiece. I don't recall the thread pitch, just take your sensor down to the fastener joint.

That is all in the world that this auction for 5 bucks appears to be -- a nut

If you are using a 1 wire 02 like I am and just reading the voltage on a multi meter the spark plug anti fouler for cheveys (sold in the help section, moves the plug out a little bit) are the right things, Just cut off the one end and drill into the pipe, weld in and your good to go.

It is supposed to be in the exhaust stream but most Sensor instructions say to mount it somewhere in the system on an angle so condensation does not soak it is all.

I had bungs welded to my down pipes. After checking the A/F
I just screwed plugs in them. Never left the sensors in them.
