Details

Add some serious firepower to your Ford engine by installing our DUI Distributor! The all in one DUI (Davis Unified Ignition) has everything you need for the ignition system in one simple unit. No external coils, modules or spark boxes are needed! Just one 12 volt hot wire connected to the DUI will send 50,000 volts of pure spark energy to the plugs and light the cylinders like never before. Increased horsepower, torque and fuel mileage along with quicker starting and smoother idle are the benefits of installing the DUI. These gains are made by the high performance coil and module and custom tuning of the advance weights and springs . The high voltage coil allows spark plug gaps to be opened up to a massive .055″. The dwell in our Dyna-Module has been increased electronically to allow the coil to produce a longer duration spark. The combination of the large gap and longer spark provide the most complete combustion of the fuel mixture possible. A special weight and spring assembly is hand fitted and dialed-in using a Sun Distributor Machine for a precise timing curve that will match the specifications of your engine and vehicle. The super smooth advance provides instant throttle response and maximum power throughout the rpm range with no pre-detonation. Vacuum advance is provided for improved fuel economy and cleaner spark plugs. Installation for the hot wire and a tachometer are made simple with the included connectors. The DUI is built for durability with an upper and lower bronze bushing. Two bushings provide shaft stability for accurate trigger signals and years of trouble free operation. The oil impregnated bushings are also known to outlast ball bearings! The Ford DUI is based on the HEI (High Energy Ignition) system and although it is uniquely designed, replacement parts can be found at any local auto parts store. Don’t be fooled by the cheap imitation one wire distributors, the DUI is unsurpassed in quality and is the original one-piece ignition system for Fords!
