EP-1631 Electronic Distributor for Isuzu Trooper Buick Century Chevrolet Lumina V6

The EP-1631 is a cross-brand electronic distributor covering the Isuzu Trooper, Buick Century, and Chevrolet Lumina -- an unusual combination that reflects the shared engine architecture between GM-derived V6 engines used across these different vehicle brands in the late 1980s and early 1990s. GM supplied engines and drivetrain components to Isuzu for the Trooper, and the GM V6 family was shared across Buick, Pontiac, Oldsmobile, and Chevrolet passenger car applications.

The Isuzu Trooper in particular uses a GM-sourced V6 engine that shares distributor specifications with GM passenger car applications, making the EP-1631 one of the few distributor SKUs that bridges the Japanese SUV and American passenger car markets. This cross-brand compatibility reflects the globalization of GM's powertrain supply chain during this period.

Verify the OEM part number on your specific vehicle's existing distributor against EP-1631 references before ordering, as the cross-brand application range can vary by year and engine variant.

Every EP GM distributor is manufactured under ISO 9001:2015 certified quality management. Each unit is individually tested for cap-to-rotor alignment, pickup or optical sensor signal function, shaft seal integrity, and electrical connector specification before shipment. CE-EMC electromagnetic compatibility certification, UL listing, and UKCA conformity mark confirm compliance across all major export markets. Units ship complete with cap and rotor -- no additional components required for installation.
