I think he meant it's the only plug to get!

I haven't heard much on the Denso, but the NGK's have proven performance and reliability. In my mind, I'm not using anything else.

NGK designed the plugs especially for the 8. They are not used in any other appications. The answer to your question there is no substitute. NGK plugs are it and thats that. You can swap out the wires if you are itching to waste some money.

Perfectly stated! The NGK wires are really nice, too. I just did the swap and love the setup.
