Install our DUI Distributor and add some serious firepower to your Pontiac, Oldsmobile or Cadillac! The DUI (Davis Unified Ignition) has everything you need for the ignition in one simple unit. No external coils or spark boxes are needed. Just one 12 volt hot wire hooked up to the DUI sends 50,000 volts of pure spark energy to the plugs for a cleaner, crisper, more powerful running engine! Part of the DUI’s performance comes from the custom calibrated advance curve. 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. The DUI’s high output spark comes from our 50,000 volt coil and Dyna-Module. 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 larger gap and longer duration spark provides the most complete combustion of the fuel mixture possible for increased horsepower and torque. Additional benefits include quicker starting, smoother idle and better fuel economy! All DUI caps have the brass terminals for optimum conductivity and corrosion resistance. Whether your engine is bone stock, mildly modified or heavily modified, we can tune a DUI for you. So, don’t be fooled by the cheap rebuilt and so-called “performance” aftermarket HEI’s, insist on a quality distributor and start Driving Under the Influence of the Davis Unified Ignition!
