E3 plugs
#2
I tried them on my 76 smog 350 and didn't find them as good as the Ac-delco's. I emailed E3 and asked them why they just didn't make the car idle as good as the Delco's ,he told me they should, if I'm not happy with them then go back to the Delco's LOL.
No friendly support at that end haha.
It could just be my smog 350, I dunno!
I hope this helps.

I have used AC Delco Rapid Fire Platinums, Bosch Platinums, Autolite Copper, AC Delco Copper and NGK Copper in Olds V8's. The NGK idle the smoothest, the rest are similar since the Autolite and Delco's come from across the ocean. I may go AC Delco since NGK plugs are harder to find locally.

Not the greatest Customer Service but ...

The E3's ground electrode design seems to "shield" the arc from the combustion chamber more than most plugs. This will likely not be an advantage. I also don't like the lack of gap adjustability.

Thanks Eric, I think there may be 8 NGK XR45 plugs in my tool box. I also have Bosch Platinum in there, some Champions, Autolite's and AC Delco's. If you had some XR5 plugs, I would take you up on it. I have 7 of those and think they may work better with my 9 to 1 compression and the ton of part throttle timing I may run. Cutlassefi's custom cam may help keep detonation at bay, having 217/223 duration, so maybe the XR45's I have will work.

E3 plugs
O'Reilly Auto parts carries NGK Plugs. I had E3 plugs in my 88 Mustang and took them out cuz the 4 banger seemed to lose power. Installed Autolite plugs and didn't notice a difference. Have E3 plugs in the 69 442 and it ran great.

Everything I've heard and read concerning e3 plugs says the same thing. They're good plugs for high revving, high compression engines. On a low compression pavement crawler, they're rubbish.
