Default Nitrous plugs?

Whats the latest in greatest for plugs for 100 shot of nitrous? Right now I've got AC Delco Rapidfire #5 in the car which are platinum and coming out asap if I decide to put the bottle in the car anytime soon. I was going to run the superceeding part # for FR2LS as I thought it was 1 heat range cooler than stock (which I thought would be the FR3LS #) but I was told it isn't.

I have clearance problems so I went with Accel Shorties (574S). They are 1 heat range cooler than stock, but I've only used 1 bottle and that was all just testing and tuning.

The AC Delco plug you would be looking for is an FR3LS6.

Scorp,
Yes I do believe that this is one heat range colder. I was told by the late Jim Formato that these were good up to a 200 shot. They worked well for me for many years and may be purchased over the counter at your local parts store.
