NGK Spark Plug Wire Sets are built to meet stringent OEM tolerances for a variety of import vehicles
a spark plug fires, it creates a great deal of radio frequency
interference (RFI) and electromagnetic interference (EMI).
Uncontrolled, this can show up as static in the radio or other
electronic devices, or much more seriously, in electronic ignitions,
fuel injection, and engine management systems. This interference with
EFI and engine management systems can cause "cross talk" between wiring
harnesses resulting in poor running, misfiring and decreased
NGK Resistor Spark Plug Wire Sets utilize a
construction method known as "variable pitch" wire winding to create
resistance to radio frequency interference. The variable pitch winding
(loose/tight/loose) provides suppression throughout a very wide range
by "scrambling" and breaking up the electrical waves radiated by the
firing of the spark plugs.
