The EIS outputs an extremely high-energy charge from the ignition coils. Spiral core wires work best with this charging method, since they prevent the electrical noise generated by the coil firing events from being transmitted. We recommend an 8mm or larger spiral core wire with a resistance of 300 ohms or greater per foot.

SOLID CORE WIRES SHOULD NEVER BE USED.

Do not be misled by spark plug wire manufacturers claiming to give you a “power increase” from their wire. The bottom line is that with our charging method, different spark plug wires simply do not make a difference in terms of spark energy. However, there is a huge difference in noise generated by different spark plug wire types (solid core wires generate a very high amount of noise with our system).

Paraphrased from Magnecor’s Website:

“What is not generally understood (or is ignored) is that the potential 45,000 plus volts (with alternating current characteristics) from the ignition coil does not flow through the entire length of fine wire used for a spiral conductor like the 1 volt DC voltage from a test ohmmeter, but flows in a magnetic field surrounding the outermost surface of the spiral windings (skin effect). The same skin effect applies equally to the same pulsating flow of current passing through carbon and solid metal conductors. A spiral conductor with a low electrical resistance measured by a 1 volt DC ohmmeter indicates, in reality, nothing other than less of the expensive fine wire is used for the conductor windings!

Electrical devices, including spark plugs, use only the electrical energy necessary to perform the function for which such devices are designed. Spark plug wires are nothing more than conductors, and whereas a bad ignition wire's inefficient conductor can reduce the flow of electricity to the spark plug, an ignition wire that reportedly generates an "increase" in spark energy will have no effect on the spark jumping across the spark plug gap, since the energy consumed at the spark plug gap won't be any more than what is needed to jump the gap. For a more obvious example of this, a 25watt light bulb won't use any more energy or produce any more light if it's screwed into a socket wired for a 1000 watt bulb.”

Due to the extremely high energy in the EIS coil charging circuit, spark plug wires may wear out faster than with a standard ignition. As such, it is recommended that the wires be checked periodically for carbon tracking caused by a breakdown of the internal conductor element. Looking at the plug wires in a dark area and wetting them with a spray bottle of water will reveal carbon tracking. Pay close attention to the exposed section of the spark plug (where the rubber boot ends) during the test. To maximize spark plug wire life, keep the lengths as short as possible (i.e. mount the coil pack as close to the engine as possible). Replacement of the wires on an annual basis is recommended for high-rpm/high-horsepower applications.

Electroair uses the Taylor Pro-Wire Silicon Resistor Spiral Wire. This wire is an extremely high-quality wire with excellent noise suppression. Each wire supplied is made up of two terminated ends for the coil posts, you just need to cut the wires to the appropriate length and terminate the end with the hardware supplied to create the spark plug end.
