With the "coil-on-plug" used on 4.7 engine, there are no aftermarket ignitions available (i.e. hotter coils). Since these 8 individual coils are fed 12 volts and the ground is interrupted by computer control to cause the spark, would it be possible to add a DC-to-DC converter to it and feed the coils a higher voltage (15-18 volt)? Any ideas on effect on spark and coil longevity?
