Spark Plug recommendation
where are you guys finding Bosch platinums for those guys? According to Bosch's book, there isn't one for EFI 300 engines.
In about 60K I've tried Autolite (which to the best of my knowledge is Motorcraft. Please prove me wrong if otherwise), Champion truck plugs, and NGK V-Power plugs. I just put the NGKs in a month ago, so I'm not sure on longevity, but they sure look a lot better than the Autolite platinums did after a month. I think I've found my favorite.
