It's time for you to start Driving Under the Influence of the D.U.I. (Davis Unified Ignition)! Drop
in one of our powerful D.U.I. Distributors and you'll feel the difference. Whether you drive a
Challenger, Charger or a Dodge Truck, the D.U.I. will improve the performance of your Dodge
engine. If you're installing a Mopar Performance crate engine, the D.U.I. is the ideal ignition
system for it.

Our D.U.I. is the only one-piece ignition system available for Dodge and Chrysler engines.
This is a simple drop-in unit with the coil inside the cap and the module inside the distributor.
Just connect one 12 volt hot wire to the distributor and you're ready to run! A tachometer hook
up is also provided. Your engine compartment will look much cleaner as the D.U.I. will eliminate
ALL of the messy wiring that is found on stock Dodge/Chrysler ignition systems.

The Dodge/Chrysler D.U.I. is available in either the Street/Strip version (up to 7000 rpms) or
the Racing version (up to 9000 rpms). Both units will allow you to run a whopping .055" spark
plug gap, which provides a more powerful burn of the fuel mixture for increased horsepower.
Our Dyna Module is designed with more dwell time which allows the coil to produce a hotter
spark. Full voltage can be run through the D.U.I. as no ballast resistor is needed. Stock Mopar
systems, and many aftermarket systems require a ballast resistor which reduces voltage in
the ignition system. Full voltage means a hotter spark at the plugs and more performance
from your Mopar.

Every D.U.I. is custom curved on a distributor machine based the specs of your engine. A super smooth advance curve will eliminate engine damaging detonation and provide instant throttle response. The Dodge D.U.I. is a real work of craftsmanship. Although it is uniquely designed, replacement parts are easy to find. GM High Energy Ignition (H.E.I.) replacement parts, available at any auto parts store, will fit right on the D.U.I. Built for durability, the D.U.I. has an upper and lower bushing, unlike stock Chrysler distributors which only have one bushing. The DUI is polished and lubed as it is assembled so that all mechanical parts perform smoothly and at their
maximum performance level.

DIMENSIONS: The DUI measures 8.5" from the block to the top of the cap. The diameter of the distributor cap is 5 1/4".
