I am trying to think ahead and take advantage I still have the manifolds in my hands rather than installed and wanted to install an EGT bung for the future, I know the size for the 02 sensor but not sure for an EGT sensor.

Would it it be the same?

Help fast as it will be going on today.

Thanks.

 

1/8 NPT

 

The way I have "bunged" both EGT and O2 is to install an O2 bung into each of both pipes and then use a threaded adapter to place the EGT into one the "larger" O2 bungs. This way during dyno tuning you can leave yourdash A/F gauge intact and screw the shops O2 sensor into the "EGT" hole. The EGT is not terribly useful on the dyno.
