Spark cap: The spark cap is a component that connects the high-voltage line and the spark plug, and its quality directly affects the starting performance of the motorcycle. In the use and maintenance of motorcycles, few people noticed the spark cap. For example, some motorcycle users simply remove the spark cap and directly connect the high-voltage line to the spark plug. Another phenomenon is that it is difficult to buy high-quality spark caps in the motorcycle parts wholesale market, because the merchants do not realize the importance of spark caps. The spark cap can improve the damping effect of the engine ignition system on the current, thereby reducing the ablation of the spark plug electrode, more effectively suppressing and attenuating the electromagnetic wave interference of the engine ignition system to the radio equipment, and prolonging the service life.High-strength aluminum alloy.Easy to install.long lasting life-time
