    Sparkplug part numbers/info

    Hey all,

    Thought Id ask a few questions about spark plugs - Does any one know of a good (web) source of info on the different plugs, what the numbers mean, etc etc?

    I know its an ADR standard these days to use 'R' type plugs for polution (BR8EG instead of B8EG) because of the resistor in them - but does anyone have any other info on the differences like what do the letters after the number relate to?

    Cheers
