NGK ignition cables have followed the development of vehicles, especially in the use of onboard electronics, and higher engine compression rates, thus requiring greater electrical charges to the spark plugs and producing more radio frequency interference. The changes in vehicle chassis has also influenced their performance, in the search for better aerodynamics, which has reduced the size of the engine compartment and increased heat. In addition, cables should be designed to resist high temperatures, high voltages, corrosion from fuel, solvents, etc.

NGK resistor Ignition Cables provide superior performance and are used as original equipment by the major car manufacturers because of the following qualities:
	Great suppression of noises and interference.
	Great electrical conductivity, no ignition failure (fuel economy).
	Durability in extreme conditions of temperatures and voltages.
	Mechanical durability .
	Resistance to fuel, oil and water attacks.
