Bullet Train Spark Plug

If you're looking for a 2-stroke spark plug made for longer life and optimum performance, the Bullet Train Spark Plug is just for you. Compared to your bike engine's stock spark plug, this spark plug will be able to handle high voltage from performance magnetos and CDI's to give you plenty of power for plenty of riding. These plugs are made from alumina silicate and offer a ceramic insulator just like the NGK B6HS spark plug. And just like NGK's, these are copper cored and triple sealed to further aid in heat removal and prevent interior leakage. That means you're getting greater strength, a better seal, and better heat transfer than other plugs out there.
