International Scout owners have almost been totally ignored by the performance ignition
manufacturers - until now! Performance Distributors now offers a D.U.I. (Davis Unified
Ignition) distributor, which is a compact, one-piece ignition system for International V8
and 4 cylinder engines. The D.U.I. is virtually water, mud and vibration proof because the
electronic components are protected inside the distributor. All you have to do is run one
12 volt hot wire to the D.U.I. and you are ready to run! A tach hookup is also provided.
The D.U.I. features a 50,000 volt coil and the high output Dyna Module. The coil and the
module work together to produce a longer duration spark, allowing spark plug gaps to
be opened up to a whopping .055" The larger spark plug gap burns the fuel mixture more
completely, leading to more power. A hotter spark also keeps your plugs cleaner longer.
The D.U.I. allows FULL voltage in the ignition system - no ballast resistor is used. Every
D.U.I. is hand assembled to exact tolerances - no mass production. Each unit is calibrated
on a distributor machine with a super smooth advance curve providing you with instant
throttle response and more power, while eliminating damaging detonation. A coordinated
vacuum advance is also utilized. No trial and error for you - the advance curve is already
dialed in. Built for durability, the D.U.I. features both an upper and lower oil impregnated
bushing. A heavy duty cap and rotor with solid brass terminals is included. Cap colors are
available in Red, Black, Blue, Yellow and Clear.

*Due to the large size of the DUI, a modified thermostat housing must be used which is
included with the distributor. The vacuum advance may need to be removed if adequate
space is not available. This can be done using the enclosed vacuum advance eliminator
plate.The International DUI is covered by a one year warranty from date of purchase.
