NGK CR2 / 8048 Spark Plug Cap Genuine NGK ComponentFeaturing a resistor element pressed in between the plug terminal and the high tension wire connection, the construction is extremely durable, the resistor element is long enough to prevent interior flashover, and steady resistance is maintained. Superlative ceramic materials are incorporated that resist deterioration and have small resistance variation under over-load, whilst the plug connector is made of sturdy phenolic resin, practically oblivious to tremendous heat and high tension, and very rugged rubber material. The heat press insertion makes the construction all the more tough and vibration-resistant. Special rubber liners on both ends prevent moisture from causing electrical leakage.BOX DIMENSIONSHeight (mm): 235Width (mm): 125Length (mm): 30 If you are unsure as to whether this is the correct part for your vehicle, please don\'t hesitate to contact us.
