But as Smokey once demonstrated, and backed up with data, what you can't hear is how often each cylinder has a partial misfire. I don't think you can solve that problem with trick spark plugs, or trick spark plug wires. I do think you can make the problem worse with the wrong spark plugs. I don't think any one company makes the best plug, or the best plug for all applications.

My readings of information from Jacob's Electronics indicates they believe they have the best solution to that common problem of misfiring cylinders. From their website:
High Performance Ignition Packs
Energy Paks are not to be confused with OEM/factory computers or simple add-on hot spark or multi-spark ignitions. Jacobs' computer controlled ignitions modify spark output in response to changing environment and running conditions. (US Patent #3,827,418). By tailoring spark voltage, duration and phase angle for each cylinder on every power stroke, all Jacobs Electronics' computer-controlled ignition systems are guaranteed to improve performance, gas mileage, engine life and lengthen intervals between tune-ups.
I've not run one of their ignition packs but did install their version of a rev limiter in my first car. Currently have a 6AL for that purpose.
