I just bought this van and wanted to change plugs and plug wires. On
some Fords I've heard that only the Motorcraft plugs will work
correctly, because of a slight difference in the size of the
insulator. Is that the case with the '94 E150? I would like to use
platinum plugs, if possible, to get the longest interval between
changes. Is there a platinum alternative for my van.
