High quality spark plug NGK CR8HSA cooler than C7HSA.
Heat rating =8 A spark plug must be able to dissipate the heat emitted by the combustion gases.
The heat rating expresses the ability of a spark plug to dissipate this heat.
The temperature in the combustion chamber is different for each engine, so a spark plug with a suitable heat rating must be used.
This number corresponds to an average temperature measured at the electrodes and the insulator.
The higher the number, the "cooler" the spark plug, so this spark plug is more suitable for hot weather
It dissipates heat better, ideal for use in summer !
Compatible on all 4 stroke mini motorcycles, approved or not.
Made in Japan !
