i have read B6ES plugs are good to use in the RG engines. I havent beeen able to find them though. B7ES, B8ES, B9ES are all there but are all colder temp range perhaps these would be better suited.
BP6ES are also common the only difference i can see is that the P stands for a protruding head?
I am also planning on talking to toyota on which plugs are suited to these motors but cannot do so until tuesday.
