i only went with the 103 to see if they would help/work good i suppose, my 104s were two years old, not that they had any where near 10,000 miles. i felt it was time to change em.

Well I just got done installing the autolite 103's and my car seems to love them. I haven't done a full blown comparison yet but I can tell it deffinately helped with the little kr I was seeing in the top of 2nd and 3rd. I will let ya know more accurately how much it helped tomorow when I can take it out longer. I also gapped them at .46 which is a little less then what's reccomend which I believe is .50 but I was running my 104s at .50 and that worked great so since this is a colder plug I figured I would shorten the gap just a tad.
