Simply put, D.U.I, is three letters you never want to hear. But with a Performance Distributors one- piece ignition system, D.U.I, is three letters you cannot do without! The D.U.I. (Davis Unified Ignition) allows you to Drive Under the Influence of more power. The newest addition to the D.U.I, distributor lineup is now available for the Toyota Landcruisers with the (2F) 258 cid in-line 6 cylinder. The D.U.I. features a high voltage coil and high dwell module which is located inside the distributor. Only one 12- volt hot wire is needed to get your engine charged with a D.U.I.

The distributor is custom tuned on a distributor machine for your engine using specs such as cam duration and lift, compression ratio, vehicle weight and octane of fuel. The high output coil and Dyna Mod module allow spark plug gaps to be opened to .055". The combination of the custom advance curve and the high output coil and module will give you
instant throttle response, quicker starts and more horsepower.

The D.U.I, is virtually waterproof making it ideal for off-road conditions. Since the electronic components are located inside the distributor, they
are not exposed to the elements of off-road conditions that will cause stock and other aftermarket ignition systems to fail.

Although the D.U.I, is uniquely designed, replacement parts are easy to find. GM H.E.I. replacement parts will fit right on the D.U.I, and these
parts can be found at your local auto parts store. An optional tach hookup is included with the D.U.I.
