Nope, tried that already, probably will go with a Bosch w8ap, which is a platinum plug. Maybe I will throw in a little extra oil to make sure the engine don't get to hot. I don't think that the w8ap is that much differnt than the w7ac though obvisoulsy it is different. I am not sure though actually now as I think about it wether the "8" is hotter on Bosch than a "7" do you know Reeperette? Tanx!
