摘要： A plug cap and a method for attaching the plug cap which prevents the occurrence of depressions on a spark plug screw thread and in a cylindrical section of the plug cap. The plug cap includes a spring pin having a straight section which engages a groove in the conductive cylindrical section of the plug cap. The plug cap also has an identifying part on its exterior which indicates the direction in which the straight section is oriented. The plug cap is installed on the spark plug in a way which orients the straight section of the spring pin in a direction parallel to the principle vibration axis of the engine. The base of the plug cap groove may also be cut to a width which dampens the effect of vibrations causing translation of the straight section within the groove. The groove sidewalls may be angled to aid in removal of the plug cap.
