Air/Fuel Mixture Tool

The bung is a problem on a stock car. I did the same though I mounted it temporary, ran the cable through a drain plug in the floor. I found I ended up the same as by doing it trial and error, it just gets you there a lot faster.

I understand. Just that the cars are show cars, not wanting to install the bungs.
Thanks Bob

What is a good brand or model of O2 sensor to mount in the exhaust?
