Give us some real information.
  • How many electrodes is best? Is it all marketing, like razors, where one is actually as good as four or does it matter?
  • Plantnum? Iridium? Copper?
  • Dimpled? Forked? Plain?
  • Check the gap, trust the manufacture, or look up a Porsche spec?
Be sure to torque them to: 30 Nm (22 ft-lbs)
And do not use anti-seize.
One electrode is all that is needed

Iridium is by far the most durable

None of that really matters

Always at least check the gap

And always use anti seize
