Industrial and Farm vehicles with the MV404 or MV446 can now benefit from high performance electronic ignition with the DUI distributor. The DUI (Davis Unified Ignition) is a one piece electronic ignition system that incorporates the coil and ignition module internally, requiring only one 12 volt hot wire for hookup. This distributor is all new from the ground up allowing you to ditch the factory ignition and all of its components. The DUI is based on the Chevrolet HEI design which makes replacement parts easy to find at your local auto parts store. The DUI distributor is built with a 50,000 volt coil and high dwell module that is capable of firing a .055″ spark plug gap. The wider gap maximizes combustion for improved performance and better fuel economy. The mechanical advance is tuned to provide an optimum power curve from idle to the maximum rpm. Paired with the high performance electronics, the DUI will produce quicker starting, smoother idle, more horsepower and added torque. So if your tired of fooling with points and unreliable electronic conversion kits for the stock distributor, step up to the DUI for maintenance free high powered ignition.

The DUI Distributor has a one year warranty from date of purchase.
