1st - You need to gap your plugs closer with nitrous to prevent missfires. Gap to 35 otherwise the juice tends to blow out the spark ('course, you don't need new plugs to do this, but they will be out anyway)

2nd - You need plugs that are one-step colder. This will help prevent detonation. Colder plugs pull more heat away from the combustion chamber.

3rd - You need to use copper. You will get a better spark and if you run lean, the copper will melt before your cyclinders.

4th - You need to read your plugs!!!!! You can't do this with old plugs. So, when you start at a 25 shot, make a few runs, and then pull one of the plugs and look for signs of detonation or lean a/f. Each time you increase your shot, pull the same plug and inspect it. Technically, you should pull of them, but I really don't think you need to take the time to do that. Lastly, you should get used to reading your plugs from time to time....it is a really good idea as you might prevent a disaster before it happens.

The Venom is the safest setup on the market. Follow these plug rules and you will be golden.

I use Autolite 103. They will cost you less then $16 for 8 plugs.
