    Comments about Autolite Platinum Spark Plug:

    This plug is being used my older Yamaha v-twin motors like in the Virago and V-star. It runs a bit hotter than standard replacement plugs, and fires more completely through the combustion cycle. Best part is it runs best with regular 87 gas! Google it and see how good this plug is. I haven't used it in any cars, but I would!
