A coil-on-plug Ford Modular engine making significantly more power than stock can outrun the spark energy the factory coils were designed to deliver, which shows up as a misfire under boost or nitrous. This booster raises the peak current at the coil and the spark energy at the plug by about 20 percent over stock, and it plugs into the factory coil connectors and harness so nothing has to be cut. A two-step rev limiter is built in for launch control.
