Why do you have to change them every time you change your oil? Mine have almost 10000m on them, and are fine. [NGK BKR6E]

BKR6E = Stock, I dont think copper?

Most people reference BKR7E copper plugs to change every 5000miles. On the stock plugs I began to have some troubles at about 200awhp. I've since changed to the coppers, and now making ~250awhp and running great.
