I have run the standard HD plugs, NGK and now have the platinum HDs at the suggestion of the local indy, and I couldn't tell any difference between them.

All I have ever used are the stock HD plugs and never had any issues. Just me.

I run DCPR8E by NGK because it's a one step cooler plug. There's arguments for and against ,which I'll avoid, but it works for me.
