Hey all, I was looking for a set of aftermarket ignition wires in a different color just to add a little dress up under the hood. I found these Livewires that come in a sort of Ford Blue color. I also noticed the screamin demon coil and I was wondering if anyone has ever used it and what you thought about it? Most importantly will it require a change in tune?
