NGK CR9E Spark Plug

 

This spark plug is made to run cooler than the factory unit. It is perfect for high compression and modified Grom engines as a means to ensure the engine remains running smoothly, as factory units can wear out and the spark become weak, resulting in misfires and loss of power. The plug is also shorter than the stock unit as it does not have the protruding insulator, which is perfect for high compression engines or custom makes.
