      A:

      The spark plug gap, along with the combustion chamber pressure and the ignition timing has a direct bearing on the amount of voltage you require from the ignition system.The bigger the spark plug gap, the more voltage you require to have the spark arc across the gap. The same applies when the combustion chamber pressure is increased. The spark plug gap also has a bearing on engine performance.The recommended spark plug gap is designed to be adequate for cold starting and smooth driving on a car that is in need of an engine tune up.
