Because the DUI Coil and Dyna-Module produce a longer duration spark, you can open the spark plug gaps to .055", burning fuel more completely. The DUI utilizes a brass terminal cap and rotor, insuring maximum conductivity.

Every distributor is calibrated on a distributor machine that will give you the instant throttle response that other off-the-shelf distributors will not provide. A very smooth advance curve is dialed in, whether it be for performance cruising or all out racing.

Our marine distributors are blueprinted. Each one is polished, lubed and checked for exact tolerances as they are assembled. Flame arrestors are installed on each housing.

The GM and Ford Marine DUI is available in two versions. The Marine-7000 version is designed to provide superior performance for stock to mildly modified engines up to 7000 rpms. The Marine-9000 version is built for high performance and racing engines up to 9000 rpms.

Performance Distributors is now building the one-piece DUI Distributor for Marine EFI motors. Converting your remote mount coil that comes on many of today's EFI engines, is easy and will bulletproof your ignition system. It will also reduce your wiring to a bare minimum. A plug-in adapter is also included.

If space is a factor with your E.F.I. Chevy, use the remote mount coil style distributor. This system includes the high output Dyna-Module and brass terminal cap and rotor. The Screamin' Demon Coil allows you to open the spark plug gaps to .060", burning your fuel more completely.
