What is fire ringed and O ringed?

[highersmoke24v]

What exactly is fire ringed and O ringed? What are the advantages and disadvantages of each? At what point do you need to do either one of these? About how much does it cost? I have heard this for a while and just don't really know what its talking about.

Oh so thats what it is. No but really can anybody give me some idea of what this is?

There another thread outlining the differences and even some price talks. I believe its in the "Dodge Competition and Performance" section
