I'm about to do a tune up on my 98 GT. I'm going to purchase the ford racing wires and the basic motorcraft plugs-my question is about the coils-I was looking at the screaming demons-are they worth buying or should I just do the stock replacement ?? I can't afford the MSD or accel so are the demons a good choice? The price seems awesome and if they perform as well as they say they seem good . Just a few words of wisdom from someone would be cool. Thanks
