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.
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.
