Thread Pitch for O2 sensor holes

I'm using a FM Micro tuner that doesn't use the sensors. Does anyone know off-hand the thread pitch for the sensor holes so I can plug them?
Thanks

I think that they're 18x1.5 mm but generally you just unplug the sensors and go from there. I know many just "wrap" the sensor leads and that's it.

18MM-1.5.

I had to clean up the threads on a used set of pipes that I bought for cheap.

I got tired of the wires hanging out so I went to the hardware aisle at Lowes. Found some M18x 1.5 oil drain plugs that look great. Installed with loctite.
