D.U.I. Distributor

(w/ Vacuum Advance)

Performance Distributors one-piece ignition system, D.U.I. are 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 From LC Engineering.

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 high output coil and Dyna Mod module allow spark plug gaps to be opened up 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. Each Performance Distributor is custom-tuned on a distributor machine with a super smooth advance curve. A custom advance curve insures maximum performance and mileage. Buying an "uncurved" distributor would be like buying an unground camshaft! No compromise curves...no guesswork for you. Just pure power from the world's leader in high-performance advance curves.

5 of 5 Easiest distributer install ever January 20, 2022
Reviewer: Jamie Mcginnis from Glide, OR United States  
I was hesitant to attempt to install this due to the lack of provided instructions but it turned out to be the simplest install I've ever  done. Just reuse the switched 12V ignition wire "brown in my case" from the stock coil hooked to the distributor labeled "battery", set timing and your good to go. Helped with some of the flat spots in my throttle and feels much more responsive over the stock coil setup. Worth the investment and gives plenty of room for upgrades down the road. Pairs well with a set of livewires.

5 of 5 Beast of a distributor April 15, 2019
Reviewer: Bradley Goforth from Maryville , TN United States  
easy swap for the average mechanic if you know anything about a GM HEI distributor then it’s exactly like it and the instructions are for a GM as well. They provide OEM quality connectors for you to give it a factory look with your custom wiring. I am very happy with it
