Delphi CZ20007 Distributor

Ignition Distributor for GM V6 Applications

The Delphi CZ20007 distributor is built for GM vehicles that use a computer-controlled ignition system with horizontal HV towers for V6 applications. It includes the distributor cap and ignition rotor, giving you the core components needed for a clean ignition service on select Chevrolet, GMC, and Oldsmobile models.

Delphi brings OE heritage and application knowledge to this aftermarket distributor, drawing on more than 100 years of original equipment experience. If you are replacing a worn distributor on a Chevrolet Astro, GMC Safari, or Chevrolet Blazer, the CZ20007 is built around the factory-style interface and ignition layout.
