Description
The D.U.I. is a one-piece ignition system with the coil in the distributor cap and the module inside the distributor. The D.U.I. Coil produces 50,000 volts and allows spark plug gaps to be opened up to .050" - .055". The Performance Distributors Dyna-Module has more electronic dwell time in it to give the coil more saturation time to produce a hotter spark. The D.U.I. distributor eliminates the ballast resistor that is used on the stock AMC ignition system to allow full alternator voltage through the ignition system, allowing better spark and more power.
