Autolite 3923 spark plugs are slightly shorter in length and are one step colder than OEM plugs - this means that their spark isn't quite as hot, which will lead to less detonation in hot weather or under heavy load. Some parts stores will try to give you crap over the selection because they aren't OEM style, but a lot of people use them just fine.
