Dang, what did I walk into? I've never heard anything bad about the E3's. I put them in my Hemi, back to backed them against Autolites, nothing changed. I even put them in my 6.0 Suburban. Now I'm going to have to look into this. The Hemi still has them in. I don't know what to think, now. I like them. My engines seem to like them. I'll do some research tomorrow.
