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.

Detailed Description

The Delphi CZ20007 is a distributor assembly for GM ignition systems that require a sealed 3-pin connection and horizontal high-voltage tower layout. It is engineered for vehicles such as the Chevrolet Astro, GMC Safari, Chevrolet Blazer, Chevrolet S10, GMC Sonoma, and related V6 platforms listed in the fitment data. This part number, CZ20007, is also referenced in aftermarket catalogs under several interchange numbers for the same application.

This part cross-references WAI DST1639 and TechSmart Z95002 for the same application.

What It Helps Address

  • Hard starting caused by a worn distributor assembly
  • Misfire concerns related to distributor cap or rotor wear
  • Rough idle from inconsistent ignition signal delivery
  • Intermittent spark issues in computer-controlled ignition systems
  • Ignition service needs on GM V6 trucks and vans

Installation Notes and Tips

  • Verify the 3-pin sealed connector and horizontal HV tower layout before installation.
  • Transfer or connect the ignition coil separately, since the coil is not included.
  • Use the existing plug wire set where required by the vehicle application.
  • Confirm timing and ignition system settings after installation on computer-controlled systems.
  • Review the vehicle-specific fitment for Chevrolet Astro, GMC Safari, Chevrolet Blazer, and other listed models before ordering.
