I've always read that it's best to stick with Motorcrafts, but I know there are a couple guys on here that run E3's and are pleased with them. Hopefully they'll chime in.

I tried a similar looking plug way back when that was called "Blue Flame" or something like that that had a triple ground for the spark to jump to, these look a lot like those. They did nothing for me. I have found that Autolite or Motorcraft plugs give the best performance for me. If you try them keep us posted on the results.
I have these plugs installed in my truck and I like them. They have improved throttle response a little and they claim to improve gas mileage. I like them and I would recommend them if somebody wanted to try something else besides motorcraft.
