What do you look for in a race distributor? Probably the first thing is spark power, then overall performance, and finally ease of installation. Performance Distributors has created drop-in, all-in-one spark machines capable of spinning 10,000 rpm! GM Racing D.U.I. distributors incorporate a spark module, inductance coil, and distributor into one simple and strong performance piece. Their built-in ignition module and high-energy coil mean that no external spark boxes or coils are needed; with just one 12 V wire hookup, you're ready to run. These Racing D.U.I.s produce a more intense spark for a more complete burn and more horsepower with minimal amperage draw off of the battery--only 2 to 3 amps. Experience and technology have led Performance Distributors to develop power-producing systems tuned to give you better throttle response and more power. These brand new units have housings that are CNC-machined from billet aluminum and feature two sets of bushings for driveshaft stability. They're available with or without vacuum advance. And, to make them even more appealing, Performance Distributors offers them with blue, black, red, and yellow caps—plus a clear cap so you can watch the sparks fly on your way to more horsepower! See the sparks and turn the revs for your racing powerhouse with GM Racing D.U.I. distributors from Performance Distributors. Order the model designed for your vehicle application.
