if you believe everything you hear, look at splitfire spark plugs for example and how much of a flop they turned out to be after everyone who bought a set never bought a second set.

I have built many Tesla coils, amplifiers, so on and so forth...

So we have ignition secondary coil which is L, a resistor, R and a capacitor which is chassis grounded, C.

RLC circuit. RLC circuits are resonant based on the component ratings in the system

The ignition coils output is AC.

If the capacitor is grounded you create a crossover, and will bleed current out to ground, since AC can pass through a capacitor. So, it can't work that way.

Now the pulstar plug is in parallel with the coil. When running AC current to a capacitor, it takes 50% longer to charge the capacitor to full pontential. Most of the energy sent from the coil is going to go across the small gap of the spark plug, so it will take even LONGER to charge the capacitor. I am not going to waste my time doing the math here, but how many ignition events does it take before the capacitor even has enough voltage potential to jump the gap? 100? 50?

In reality, with a setup like this, you may get one capacitive discharge even after lord knows how many ignition events have occured and then it has to charge again. Since one end of the secondary ignition coil is grounded, this works, but it is still COMPLETELY useless.

A capacitor on the primary coil side of the ignition coil is much more effective and actually works for every ignition event, thus why we have CAPACITIVE DISCHARGE BOXES on the market!

lol i will stick with ngk egv series plugs ( no resistors ) for my cars.

Sorry to revive and old tread. It was fun reading and i just got smarter. Don't get me wrong, I have used nothing but ngk for my 7. I just got bored and start reading old thread.
