Spark plug fixed terminal NGK BR10ES / 4684 - Suppressor cap

NGK BR10ES 4684 heat range 10 Spark plug with fixed terminal for motorcycle and scooter

The NGK BR10ES Spark plug, with reference 4684, belongs to NGK's Standard range and is designed to provide reliable ignition and proper heat dissipation in compatible engines. Its heat range 10 corresponds to a cold Spark plug, intended for engines and setups that operate at high temperatures.

It incorporates a center electrode with copper core, which promotes heat dissipation and helps maintain proper operating conditions. Its electrode features a conventional construction with a nickel tip and a single ground electrode.

The NGK BR10ES also incorporates a 5 kΩ suppressor resistance, which helps reduce electromagnetic interference generated by the ignition system. It features an alumina silicate ceramic insulator, designed to withstand the thermal and electrical demands of engine operation.

This version includes a fixed upper terminal, so it does not have a removable nut. It is important to check that the Spark plug cap is compatible with this type of connection before installation.
