Sup guys, well im installing my pacesetters as we speak. I pulled my plugs and the gap is at .70. What plugs are the best to use and what gap are you guys using? Also would the correct gap make it run better?

thanks

.7 is damn near 3/4", is the car running right?

I ran a 13.1 on those plugs. think it will be better with the right gap?

He's trying to say that it would be darn near impossible for your plugs to be gapped at .7, or seven tenths of an inch. That would mean your plug gap would be something like this [............]. Not to any certain scale or measurement, just an estimation. Your plug gap is .070. Anyways, playing with the gap a little certainly wouldn't hurt, and if it does hurt your performance, gap them back to .070 Oh, that's a pretty good time there by the way

Very easily they could have a 70 thousandths gap, if they are AC Platinums. They have a little puck on the electrode and when it falls off you have a larger gap. Both of my LT1 cars (C4 Vette and Z) had those plugs and the same thing was the case. Smoothed out when I changed the plugs.

right, seventy thousanths is not big deal, but seventy hundreths?
seven tenths? seven hundred thousanths?
little much Sorry, not trying to be a jerk or anything.
