I never said coppers make more power. Spark is spark, as long as its sufficient to create full combustion it really doesn't matter. 1 electrode plugs to 1 million electrode plugs bugger all difference. Electricity will always take the path of least resistance. Coppers are cheap, they work fine at higher levels of power than 90% of people will see and if changing cheap plugs every 5000 kms is to hard then pay an exorbitant amount for fully sick plugs for your street car (we are talking about street cars here)
