I have been using a blue coil pack on my v6 ford. It performed better than the stock unit. I even tried a new black motorcraft unit and it wasn' t as good.
Now i have seen and ordered a red coil pack. I saw somewhere describe the colors and say red is best with blue for weak spark. I also see some manufactures sell the same model in different colors.
The manufacturers of the red model also have a black one for much less money. They do not provide very much specs for them.
