    On my supercharged 355, 13psi I am going to run heat range 7, ngk plug. standard is 6.

    Heat range works differently on bosch plugs though apparently. higher numbers are colder on ngk, bosch is other way around so I was told.
    If your going to burn the aussie flag please do us a favour and wrap yourself in it first
