I got the plugs in Feb. I believe. I think there are about 5000 or so miles on them. Next time I change them out I'll go w/ the 6's. Will there be any diff. in performance getting them? Perhaps maybe getting better performance since thats what I should be using. Not to worried about it since my car runs good anyway, I just thought I would check up on them and see how things are with them.
When should my wires and plugs be replaced?
