The NGK SB05F is a resistor spark plug cap with a 5 kOhms resistor and a threaded spark plug terminal. It is suitable for a 14 mm plug thread.
The resistor element sits between the plug terminal and the high-tension wire connection. The construction includes ceramic materials, a phenolic resin plug connector and rubber. Heat-press insertion adds vibration resistance, while rubber liners at both ends are designed to prevent moisture from causing electrical leakage.
The resistor cap is designed to suppress electrical noise. Its resistor element is long enough to prevent interior flashover, and the cap maintains steady resistance.
