I guess the bigger question is, do you trust Cam or not? If you do, do what he says. If you don't, then do some searches here on the forum for what others are using. Here's a good thread:

You beat me to this, I was thinking of asking the same question just for my own knowledge but I did't want you thinking I was second guessing you or his decision.

Well then I guess you're crazy

They're a completely different plug and cost over triple what the FD plugs do.

The Rx-8s plugs have less reach than the Rx-7. Generally closer the better( obviously without contact) Here is a pic...
