In the red-hot world of performance ignition wires, Nology HotWires are white-hot. Their HotWires come engineered with a special built-in capacitor, which creates a spark that is 300 times more powerful than your typical wire. Here's how. The wire's unique design allows energy from the ignition coil to accumulate in the capacitor until the voltage at the spark plug electrodes reaches the ionization point. The entire power of the stored spark is discharged at once. The result is faster, more complete combustion, and more horsepower.
