n/a 2 steps colder? I bought a 99 z28 and there was spark plugs 2 steps colder for the zex nitrous system installed, I don't plan on using the nitrous for a long time, r there any benefits to using 2 steps colder spark plug? Safe? More or less horsepower?
Yes you can run the colder plugs. The only risk is that they will be more prone to fouling in continuous low rpm operation. In theory, there is power to be made by running the coldest plug that will not foul if it permits more aggressive tuning parameters such as spark advance. The amount that can gained is minimal when it comes to computer controlled, fuel-injected engines.
