About the product
The NGK SB05E is a black resistor spark plug cap, part number 8374. Its resistor element is pressed between the plug terminal and the high-tension wire connection.
The resistor element is long enough to prevent interior flashover, and steady resistance is maintained. Ceramic materials resist deterioration and have small resistance variation under overload. The plug connector is made of phenolic resin, with rubber material in the construction.
Heat-press insertion makes the construction vibration-resistant. Rubber liners at both ends prevent moisture from causing electrical leakage.
