What spark plugs are you guys running?

[Dope 97GT]

I am upgrading to a Vortech V-1 and I was just wondering what plugs you guys think would work best with this application.

The instructions say to run stock plugs but should I run copper with it or platinum? I have a set of NGK Iridium IX plugs that I did not install but should I be running colder plugs or copper?

Just wondering what you FI guys are running?

most people will swear by the NGK tr6's but those made my car run like total crap after a month or two

i now run motocraft awsf 22c's which are one heat range colder i think

edit: @ .035

Will it be a bad idea to run the NGKs I have?

I have those Bosche 4 prong thingamajiggers... and have no problems with missing as I did earlier. I'm running on the rich side, and I think I foul plugs easy, so the extra prongs help.

I run NGK BR7EF's w/ no problems. Just replace them every 10k.

AWSF have been replaced by AGSF as the recommended series of Motorcraft plug, probably due to the spark plug blowout issue.

I use AGSF-32C @ .054
