NGK LB05F-R / LB05FR / 8854 Spark Plug Cap Genuine NGK Component Featuring a resistor element pressed in between the plug terminal & the high tension wire connection, the construction is extremely durable, the resistor element is long enough to prevent interior flashover, & steady resistance is maintained. Superlative ceramic materials are incorporated that resist deterioration & have small resistance variation under over-load, whilst the plug connector is made from sturdy phenolic resin, practically oblivious to tremendous heat & high tension, & very rugged rubber material. The heat press insertion makes the construction all the more tough & vibration-resistant. Special rubber liners on both ends prevent moisture from causing electrical leakage.
