Ok, I found this item today while searching for ignition coil info. It is a coil targeted for ford applications but is built like the Kawasaki coil. Should be easy to get info for its operating requirements since it replaces the oem COP on many ford and Mazda applications. Its completely redesigned and cost is from $60 each. I like this setup because you can just use the standard hold down tabs used for twin plug lowers. No need to fabricate a bracket or modify your valve covers.
