So Shane, your saying the autolite dp's are more efficient than the iridiums? Hmm, glad to hear that. I'm still thinking about trying the U-grooves. Looks like its down to the motorcraft finewires and the U-grooves...

Well.... they are better than iridium's with 100,000 miles on them. Both new, I don't know, LOL. I bought the Escape with about 60,000 miles on it IIRC.
