You will not notice any difference The coil can put out about 40,000 K volts but only needs to run the bike on about 7000K volts. Nology wire would be great to carry the voltage but would not be needed HOwever a spark plug can make a difference in longevity but not horsepower I use a NGK Iridium plug in the Majesty and on my Harley as they can handle a lot of voltage (IF NEEDED) and will last a long time as the gap will not wear out or need adjustment for a long time.
