Factory wires are motorcraft also. The replacement from the dealer, also Motorcraft, and the correct ones (verified with VIN#) are about 3 inches longer in some of the cylinders. For the left bank (driver´s side) is no issue but for the right bank (passenger side) the fit is tight and can´t be loose, there are parts where you don´t want the wires to be close to, EGR and earth wire. So the extra inches make a bump, if you can say that, at the coil and the installation isn´t like factory. It works thou. I just wanted to know if there was an alternate route. This set of cables are listed for the 2002-2010 Ford Explorers, so maybe that is why they are longer so the could fit both generations.
