I just installed a set. Just curious what people have to say about them. And o btw, plug change is a very uncomfortable job lol. I'm used to working on vehicles that have much easier access! It wasn't hard mind you, just painful!
41-993 ac plugs. Who runs them?

OBS Jedi-Do Good
they are oem platinum plugs they should do you fine for 100000 miles. i use autolites which are just as good if not better but going plain copper core no platinum. for better conductor of spark energy. i do change them often more because msd will eat them up. however i had to pull one out a fewdays ago thinking i burned one up to misfire.(was the dizzy cap. again!) plug was at.068 and still working. will change them all in a week. damn good igntion system. next round is autolite extremes they should last at least 80 thousand miles.
