The Firepower Ignition upgrade for this 5.2L Magnum small-block included heavy-duty Live Wires, a Screamin' Demon coil, and a cap and rotor. The Live Wires have a heat-resistant sleeving, which protects the plug wires from temperatures of -76ºF to 1,400ºF. These wires must be used when running a Screamin' Demon coil, which will allow the spark plug gaps to be opened up for a larger spark and better fuel burn.
