Just received a new set of Motorcraft WR6103 spark plug wires. Wires are cabled together with plastic clips just like original ones and each wire has the plug number printed on it. The #2 plug boot is an off white color not black like the originals or the other 5 boots on the other wires. Saw a similar set of used wires on EBAY with one plug boot an off white color. WHAT GIVES? Could see something like this to identify the #1 plug but this is definately the #2 plug boot.
