Davis Unified Ignition D.U.I. International Distributors

Performance Distributors is proud to offer the D.U.I. (Davis Unified Ignition) distributor for International V8 engines! The D.U.I. is a one-piece ignition system incorporating the coil and module inside the distributor. Only one 12-volt hot wire is needed for hookup. The D.U.I. features a 50,000-volt coil and the high dwell Dyna Module. These components work together to produce a longer-duration spark that is strong enough to fire a massive .055″ spark plug gap!
