My old Renix is quite happy and able to break sufficient parts running the Champion RC9YC at an 0.035" gap.
I know I'd get about a 500 hp gain running the E3s and some snake oil in the wire boots; but the extra weight of the electrodes consumes about 600 hp so dollars for donuts the Champions work best for me.

I ran Champion copper for about a week when the jeep started running like crap. Pulled the plugs and one of the chipped within 100 miles. Replaced them with ac delco and have had 0 problems for 4-5 months.

Yes all the plug wires were connected correctly along with ends on cap. Well after that i swapped back in the good ol' champions slabbed a bit of antisieze on em and gapped to .50 due to my upgrades i have. Jeep runs awesome now, pickup is a lot better along with idle amd startup! Next is a better coil and i should have a pretty good setup i hope!!

For those of you with Renix systems, the coil and ignition module is an old GM style.
