Is it possible to add an interval every 4 characters in vi? And if so, what is a good google search term to learn to do such things?

To add a space every 4 characters, you can use the following command (at least in VIM):

:% s / \ (.... \) / \ 1 / g

If you use Google "VIM Substitution", you should get some useful examples.
