I think I've read every spark plug post so I should know this, but the only one I'm sure of is the Champion plug. If Motorcraft has redesigned their plug I'd like to stay with them, but I'm not sure. I'm getting closer to doing mine. My Lisle tool showed up yesterday, so now it's time to get the plugs and start running some seafoam through my gas. Hopefully I'll be one of the lucky ones and not have any break, but with my Lisle, it shouldn't matter that much. Thanks guys.

new motorcrafts are two pieces instead of three.... so they had improved it. :rollingeyes:

Anyone know if the E3 or Autolites are one piece?

Okay, so I did a little more digging. I see that Champion and E3 are one piece designs. Autolight has a crimped on shield and not welded. I don't know if this is better or not. I see the Motorcraft plug has been improved as Picaflor commented on, but is this one considered break proof or is it still a risk? I would prefer to use a one piece so I never have to worry about this again. Thoughts?

I do know the E3 is junk...

I would stick with the motorcrafts for a n/a engine otherwise the brisk plugs are not to bad for modified engines It seems like the champions, e3s, and autolites have mixed reviews.

I was under the impression that Autolight and motorcraft are one in the same, am I wrong on this? because the 2 look damn near the same.

Torqgasm, what makes u say the e3 plugs are junk?

picaflor

Look for E3 in the forum... somebody post pics of the sparkplugs and the manufacture of them was awful.

picaflor

found it!
