The Fox Pro #8 is a cold plug.

The OS #8 and the Tower Power plug sure look just alike. I use them both and they run alike too. The only way to tell the difference is that the OS plugs have an 8 on the flat.

OS #8 and Tower Power plugs are not short reach. They are about half way between a short and a long. they are considered to be a hot plug but being recessed up in the head like that probably takes a little effective heat away from them?

Enjoy,
