Would you like to add a set of DUI Livewire Spark Plug Wires?

Davis Unified Igntion’s AMC DUI Distributor is one of the best selling ignition systems we offer, and is Made in the USA! This is due to the simple one piece design, easy installation and performance enhancements over a stock ignition system. The all-in-one DUI replaces the weak three component system that came standard on the AMC engines and utilizes only one 12 volt hot wire for hookup. The DUI is equipped with an internal 50,000 volt coil, which will fire a spark plug gap as large as .055?! Their high dwell Dyna-Module, located inside the distributor, increases spark duration for improvements in throttle response and low end power. The DUI centrifugal advance system utilizes a high performance weight and spring assembly engineered for super smooth operation. The mechanical advance is then tuned using a Sun distributor machine to ensure a precise timing curve that will provide maximum power throughout the RPM range while eliminating engine damaging detonation. An adjustment free vacuum advance canister is selected to work with the centrifugal advance for better drivability and increased fuel mileage. Ballast resistors are not required for the DUI as this system works best with full alternator voltage. 

GM High Energy Ignition (H.E.I.) parts such as a coil, module, cap or rotor will fit right on the D.U.I. These parts can be found at any local auto parts store. This Street/Strip version is designed for a maximum of 7000 rpm’s and works great for off-road vehicles, daily drivers and drag cars. For more radical engines that turn over 7000 rpm’s we have the racing version, capable of spinning up to 10,000 rpm’s (contact us for the racing version).

Please note that DUI Distributors may not be ready for immediate shipping. The attention to quality and detail requires us to build each unit per order, and due to this process orders can take 3-4 weeks to complete before shipping out. During our busy season (March-September), build times can take slightly longer.
