I was hoping you chime in.
I forgot his name...maybe it was matt kenseth truck series, he just won and he does use non resistor plugs.
Has he won as many championships, no, but is cause of the plugs, no and who knows anyways...driving/pit strategy is a major part, but the motor has to stay together too and the rules are tight, not much if any diff between those engines....which at the same time makes the case of power increase if any the plugs affect.
If it was so important the mopar bible would tell you to run non resistors gap'd .100 and run coat hangers for wires.
I'm so burnt out on this.
