RC-X140 NGK Spark Plug Caps
The NGK range of resistor covers are designed to give perfect noise
suppression across all frequencies whilst engine performance is not
adversely affected whatsoever. Some caps are none resistor such as the
LZFH & LBER. Ideal for magnetos ignition etc. 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. The
heat press insertion makes the construction all the more tough and
vibration-resistance. Special rubber liners on both ends prevent moisture
from causing electrical leakage. All motorcycle manufacturers now comply
with current legislation which demands a standard of noise suppression on
every vehicle. This is achieved usually by fitting NGK resistor covers
though in many cases a combination of NGK resistor covers and NGK resistor
spark plugs (R type) is necessary to satisfy the ministry tests. It is
emphasized that despite the use of both resistor covers and spark plugs in
such engines, due to the unique and superior construction of NGK products
there is no loss of performance or shortening of service life. LB05EMH and
SD05FM being of tough EDPM rubber construction are intended for
competition/trial applications.
