I searched the forum and I can't believe this hasn't been discussed yet. Read the advantages here: https://www.rockauto.com/en/moreinfo...30635&jsn=1069 Better ignitability & longer life than either platinum or iridium.

They even have a completely different design for the SRT-6 to address the high cylinder pressure environment. https://www.rockauto.com/en/moreinfo...44196&jsn=1063

I for one am won over by their arguments. It seems to be the next step in materials and design and if upon inspection I need new plugs, well then Ruthenium it is.
