NGK Resistor Spark Plug Cap TB05EMA 14mm Nut Terminal Black (8636)

The NGK TB05EMA is a spark plug cap with a 14mm nut terminal, identified by part number 8636. Its resistor element sits between the plug terminal and the high-tension wire connection, and is long enough to prevent interior flashover.

The construction incorporates ceramic materials, a sturdy phenolic resin plug connector and rubber. The resistor maintains steady resistance, with small variation under overload. Heat-press insertion makes the construction vibration-resistant, while rubber liners at both ends help prevent moisture from causing electrical leakage. Check the cross-reference information if unsure whether this is the correct part for your vehicle.
