I'm currently installing a NX kit. I know you should not use platinum, copper, or fine tipped plugs, but is anyone running any Denso Iridium plugs with nitrous and if you are are they colder plugs or just regular. I currently have the Denso's and I had O'Reillys order the Motorcraft AWSFA-12c which I've had multiple people suggest as the best type plug for nitrous. They won't be in for a week though.
