Don’t Cheat Your Engine Out Of Any Firepower Available

Brass terminals achieve maximum conductivity

Don’t cheat your engine out of any firepower available! The DUI cap and rotor is the finest quality made today. This kit offers up to 50% higher dielectric strength and can handle all of the voltage available from the coil. Built with Brass Terminals for maximum conductivity with an improved design in the rotor for eliminating burn-through. The material used in this kit has proven to be the ideal resin for caps and rotors for DUI and HEI distributors. Nylon rotor screws are included and eliminate a “ground” for the voltage to jump at high RPM’s. Fits all V8 DUI Distributors.
