Nology ProFire High Performance Ignition Coil Wire Kit for Honda MSX Grom 125 ProFire ignition coils are on the cutting edge of technology. In order to supply the energy needed for trouble free high performance and high rpm operation, they were especially designed to have the quickest rise time with substantial energy reserves.f The available spark voltage is in excess of 45,000 volts over the entire rpm range, and spark energy is equally impressive. Despite their size, the energy storage capability and power reserves of ProFire are extra high. ProFire will deliver just the kind of spark you need for maximum performance. Kit includes Nology HotWires which are the most technologically advanced ignition wires available. HotWires create the most powerful spark possible. Eengineered with a special built-in capacitor, exclusive only to HotWires. This revolutionary design allows energy from the ignition coil to accumulate in the capacitor until the voltage at the spark plug electrodes reaches the ionization point. At that split second point the entire power of the stored spark is discharged at once, creating a spark 300 times more powerful.
