: WITHOUT GETTING INTO TO MUCH QUANTUM PHYSICS OR ANY FOR THE BENIFIT OF OTHERS. THE VOLTAGE CHARGE TRAVELING THROUGH THE PLUG WIRE HAS TO OVERCOME A RESITENCE EQUAL TO THE SQUARE OF THE DISTANCE OF THE CROSS SECTION AREA OF SAID WIRE. TYPICALY CALLED AN "OHM". WHAT THAT MEANS IS THIS. THE GREATER THE GAUGE OF WIRE I.E. 12 GAUGE VS. 14 GAUGE (REMEMBER THE HIGHER THE NO. THE SMALLER THE CROSS SECTIONAL AREA) THE MORE RESISTANCE. BUT THERE IS A FLIP SIDE "DEGRADATION" THE HIGHER GAUGE WIRE CAN NOT HOLD THE VOLTAGE REQUIRED FOR THIS PATICULAR APPLICATION. WITH LESS CROSS SECTIONAL AREA THE WIRE BURNS OUT. I WILL GET TO THE POINT. WHAT YOU NEED IS A SUFFECIENT GAUGE OF WIRE WITH THE BEST INSULATION ( TO KEEP THE CHARGE FROM "JUMPING" ).I.E. SILICON BASED WIRE WITH COPPER.

Remember the plugs have about 4-5k of resistance. 2 feet of #20 gauge (that what the factory wire look like to me), must be about .2 ohms. I'm more concerned about insulation, because the current is pretty low compared to the wire diameter. So I just got the Beru's.
For some reason I didn't get a loom. It was easy enough to fish the wires through with a hooked piece of copper wire once I unscrewed the ceramic ends.
If you want a big spark in a high impeadance system, you need more KV's. Maybe a high performance ignition system?
I'm told the factory Bosch is pretty hot though. (transistorized system)
