Racing spark plug R6254E-105

R6254E-105 racing spark plugs with long thread, thermal rating 10.5 for racing use.

These spark plugs feature a platinum alloy in the centre electrode, which ensures a more consistent spark plug performance over the entire service life, even under the most demanding conditions.

thanks to the narrow centre electrode, less voltage is required for the spark gap, making it easier for the ignition coil to work and guaranteeing optimum combustion, perfect for racing bikes or high-level pre-rides.

Check that the spark plug is the one recommended by the manufacturer
