Correct Spark plugs are much more important than we may realize. "If it fits the hole- use 'em!" Heat range is very important. If you Google "spark plud heat range"you will find some very good articles. Mopar Muscle has a good one explaining reading your plugs and selecting the correct range. Basically , to hot a plug will keep your plugs clean but leads to detonition wich then leads to serious engine danage Such as welding specks of aluminum piston to the plug insulator and dieseling. Cold plugs will allow for more advance, but will not self clean as well. Useing Nitrous or turbo- blower boost will require a significant change in heat range from the stock recommendations.
