Description
Genuine NGK LZ05F Resistor Spark plug cap black (8368) 90 Degree elbow type
Imported from Japan
5 Ohms of resistance
For spark plugs with the small terminal stud with no cap as pictured
This cap (LZ05F) replaces and superceedes these spark plug caps:
LB05F
LD05F
Suitable for spark plugs with 14mm threads (portion that screws into engine)
Featuring 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.
Due to the harsh operating environment of the resistor caps, the rubber seals preventing moisture from causing flashover can deteriorate. Regular inspection of the resistor cap in recommended and replace when there is any sign of physical damage or wear.
