i have the iridiums and well i have been told by many people that i shouldnt be useing them because they burn to hot and will eventually melt your pistons or something weird like that. im running them on 7.5mm wires and they work great, i dont know if this whole melting piston thing is true or not i was just told i should acually downgrade to a cheaper NGK like V-power or somthing that doesnt burn as hot.
