Best ''cold'' plug for a 500?

[panic]

What's on your opinion (...and experience) the most performant plug for a midly modded V8R used in a spirited way?

Thanks/G

NGK B8ECS
Used with over 150bhp of nitrous and dont foul up with 'normal' running.

If you're having trouble it's possible to see from the plug whether it's running too hot or cold. As a starting point I would stick with B7ECS for normally aspirated unless it's extremely high compression - in which case your engine builder and tuner should tell you what plugs to run.

NGK have a nice wide operating range anyways
