I searched on here and seems some say 1 range cooler for nitrous and some say no. I plan on spraying 150 with at least a +100 octane mix of 93 and race gas. probably only spray 150 at the track 15-20 runs a year. Car will be dyno tuned for the nitrous. Do I really need them with quality fuel. I still want the car to perform at its best when not on the spray. Any TRUE EXPERIANCES with the stock vs cold plugs on the spray- like to here it
