I might have to sell my powered by Ford coil divers and pick up a set of those Mach 1 ones. I have their website bookmarked but I've never seen any on a car until yours. They look pretty good.
Did you get them here?

Yup! They are nice. I wish the coil cover gasket fit on the backs better, but it works. They told me if I use some silicone on the back of the coil covers and place the gasket in its grooves, it will hold in place fine. I just haven't tried doing that yet.
