Performance Distributors is now building the one piece DUI Distributor for 1981-1995 Corvette EFI motors.
The DUI is a simple one-wire hook-up (with an optional tach connection included). Because the DUI Coil
and 7-Pin Dyna Module produce a longer duration spark, you can open up your spark plug gaps to .055”,
burning your fuel more completely. The DUI utilizes a brass terminal cap and rotor, insuring maximum
conductivity. Each distributor is lubed and checked for exact tolerances as they are hand assembled.
Each housing also is built with oil impregnated brass bushings and are lubed for durability. Also includes
the 4-prong wiring harness that plugs directly into your Vette’s computer harness.Spark up your Vette with an easy 10 more horsepower! S.O.S.-Sultans of Spark coils allow you to open
up your plug gaps to .065” burning your fuel more completely. Great to run with programmers and tuners.
Utilizes superior thermal epoxy for durability.The Chevy D.U.I. Distributor was the first, and still is the best performance H.E.I. Distributor. Inferior
copy cats have come and gone, but the D.U.I. remains the most popular choice for hot rodders
around the globe. A super smooth advance curve is machine calibrated, providing you with instant
throttle response, while eliminating engine damaging detonation. The 50,000 Volt D.U.I. Coil teams
up with our high dwell Dyna-Module, allowing you to run a massive .055” plug gap. 8, 6, & 4 cyl.
applications are available.
“Boasting 7,000 volt-per-coil advantage over stock coils, the S.O.S coil packs allow you to run plug gaps as
wide as .065” and offer improved heat and vibration resistance.”
