The NGK SD05F is a black resistor spark plug cap, with a resistor element between the plug terminal and the high-tension wire connection.
It is suitable for spark plug thread diameters of 10–12 mm and threaded spark plug terminals. Its resistance is 5 kOhms. NGK resistor caps use a ceramic resistor element, a plug connector made of phenolic resin and rubber liners at both ends. The resistor element is described as long enough to prevent interior flashover, with steady resistance maintained.
