Your vehicle requires a specific type of Chevy Impala spark plug, depending on the manufacturer's recommendation. Even though they both share the same basic function of beginning the combustion process in your engine, you may need either hot or cold plugs for your specific make and model. Hot plugs contain ceramic inserts that minimize the surface area that comes in contact with the metal part of the plug, and they run hotter than cold plugs.
