C.O.P setup, Can you make your own?

[ALLBoostAWD]

I am looking into buying/making a coil on Plug setup. Is there instructions anywhere on how to do it? What type of Coils are used for these setups, I would really like to save myself some money and try to do it myself if someone has a good write up or information about them, thanks.
