the theory behind the hot wires performance is that they are not just a spark plug wire. You can theoretically hook a normal spark plug wire to the ignition coils if you really wanted but I would agree that this would be a complete waste of time. The hotwires have a capacitor built into wire thats where they claim to have a benefit.
Tehxfallen. Don't lose complete interest. Some manufacturer make upgraded replacement coils for cars, that require no aftermarket stand alone. Spitfire makes them for a lot of nissan applications, and there is another company whose name escapes me. Not all coils are created equal, which is why you need a standalone if you are going to drastically change the characteristics of the coil. Otherwise, your ecu would control the different ignition coil sporadically.
