hey i'm going to start running a 30-50 shot of nitrous on my car and want to replace the spark plugs before doing so just to make sure everything is up to parr. im wondering what spark plugs to use because i will only occasionally run the nitrous, like when at the track ever other week.
also are there better spark plugs then others, will they help the performance of the car at all or make it start better or anything because cost isnt an issue. i've seen some platinum +4 spark plugs that look really high tech and nice.

What brand and model do you think i should use?
