I ran the NGK "9s" in my car. The Champions are good for big cylinder pressure because they have a thicker ground strap and are less likely to turn into a "glow-plug" under extreme temps. Thats one of the things that scares me about the Denso iridiums with their tiny little electrodes- much easier to get hot due to the lack of surface area.

All of my friends that run spray in there big blocks run Champions for the above reasons.
