100 shot nitrous- 2 step or 1 step colder?

[the98stang]

Hey guys I was just wondering what spark plug I should use with my 100 shot. Should I get 2 step colder plugs or 1 step colder? And what should I gap them at? Which ones will last the longest? I was thinking about getting the following plugs:

1. NKG TR6 (1 step colder)
2. Autolite 103 (1 step colder)
3. Autolite AR94 (2 step colder)
4. NKG 3P7EFS (2 step colder)

Thanks for the help!

1 Step colder... I prefer the NGK TR 6's.. I am a frequent changer of plugs (every oil change, they are only $16), but i got through 10-15lbs a week due to the track time and "OTHER" races that i have. You should change about every 9K-12K miles, and they ALWAYS look good. Always use antisieze, and trq to the proper specs. And i gap mine at .035, and no idle problems or N/A driving problems.

You don't have to go 2 steps colder until you get a HUE shot on the car..... and your 100 shot isn't a huge shot...

Ive ran autolite 103's with good luck

1 step for a 100 shot
2 steps and a couple of degrees of timing back off for a 125/150.

tr6's I had to open the gap a tad, for best na and nitrous passes. got about 15k on them and they look great, I average about 200lbs of nitrous a year give or take a bottle full.

is that the same for a 98 gt ? (NPI)

Yes, the NGK TR6s will work for you Pugh. They aren't too expensive and are a good plug.

Well I ended up getting the Autolite 103's. They were like $1.50 a piece

Don't worry Tanner you will be fine running one step colder plugs.
Just remember that they will affect you N/A.
I was running one step colder plugs on my old 92 GT with 75hp jets
on my Nitrous Express kit.
When are you installing your Nitrous Express plate system Tanner?

Today I got the bottle mounted and the plugs installed. In a few days I'll finish up
