Yo, I have a feeling that many of us with our 03-05 sunfires and cavys have had this issue. If you want to put in a new ignition for nitrous, boost, or any other performance reason, you go with an MSD DIS-2. But does anyone know how you get the plug wires from new coils to the plugs (which are buried under the big plastic plate on top of the engine w the stock coils in it.)?? Sure, you can run the plug wires right into those holes, but then what do you do with the factory ICU (i think thats what its called)?
