摘要: A spark plug may include a center electrode disposed in a center portion of the spark plug, an insulator surrounding the center electrode, and a metal shell surrounding the insulator and having a ground electrode extending downwards from a lower end of the metal shell and an inner surface facing the insulator, the inner surface being concavely shaped to form a shielding space between the concavely shaped portion of the inner surface and the insulator for adjusting a heat range of the spark plug.
