Spark Plug Replacement

You don't have to replace wires but it may be a good idea; depends on their condition.

Use a small amount of anti-sieze on the threads when you re-install them to keep them easy to remove later. Keep it off of the electrodes. You can get small packets or a whole bottle of anti-sieze at an auto parts store.

I can't recall if you remove the gasket ring or not on your year of /6; is this the original year engine?
