NGK spark plugs breaking.

I wonder how the E3 Plugs work. I want to try them. I have Auto lites and the NGK's in my cars right now. I remember trying Splitfires when I was a kid and they worked well, but everyone said they were a gimmick

I've never tried them in something without a computer, BUT I can tell you this from direct experience. I tried them in my 08 Jeep Wrangler and they made it run like it had terrible torque converter shudder. Felt like the truck was goin over a really ROUGH washboard. Put the factory Champions back in and all was well. I never wouldda believed it. I've read similar stories too. I've not seen very many people talk good about them.
