BluePrint Engines round canister ignition coils (model BPP82021BK) will outperform your stock unit's spark energy. The oil-filled design and performance construction deliver up to 45,000 volts. These coils transform the battery voltage to the much higher voltages required to operate the spark plug. The plugs then use this burst of electricity to ignite the air/fuel mixture.
