NGK SPARK PLUG - STANDARD CTN10 #-B8S

We recommend you order the correct spark plug for your bike as per the motorcycle manufacturer's specifications or the NGK spark plug finder. In many cases a higher performance spark plug may be available for your motorcycle. It may be a racing, iridium or laser iridium version. Heat Range – In NGK a lower number means the heat range is hotter. This is dependent on the original spark plug for your motorcycle. For example if the standard plug is B8ES, the hotter spark plug would be a B7ES and the colder spark plug would be a B9ES.
