The spark plug gap for a 2000 Buick Regal is 0.060 inches (1.52 mm). This is the distance between the center electrode and the ground electrode of the spark plug. The spark plug gap is important for ensuring that the spark plug fires properly and that the engine runs smoothly. If the spark plug gap is too small, the spark will not be able to jump across the gap and the engine will not start. If the spark plug gap is too large, the spark will be weak and the engine will run poorly.
