    Those are the worst spark plugs I ever had.. My car ran like absolute shit on them. Dont get drawn in with the SUPER 4's. Cheap set of ngk's and never had a problem since. Search the forum on those plugs mate cause thier are so many posts explaining the problems people have had with them.

    Best just getting ngk's instead
