Thread size on o2 sensor

[ICKY]

Anyone know the thread size for the exhaust o2 sensor? I searched but couldn't find anything specific. I'm going to put on hotshot headers. This is for an S14 btw.

just go to autozone and rent the O2 sensor socket set. It's only about $15 but you get it back when you return the set. The sockets are especially made with slots to fit the wires through - it makes it a lot easier to replace.
