Re: O2 sensor/tailpipe adapter?

[gabe <gellett@earthlink.net>]

I have a part number for a Bosch 3wire unit for about $40 that I run on my TPI,
but I am not sure this will work as the outer portion of the EGO needs to be
exposed to the oxygen outside of the exhaust pipe in order to make a comparison
between the gasses inside the tailpipe and out.
