EP-1635-4 Electronic Distributor for Chevrolet 4-Cylinder EFI Engine

The EP-1635-4 is an electronic distributor for Chevrolet 4-cylinder EFI engine applications. GM produced several 4-cylinder engines in this era across the S10 compact pickup, Cavalier, Corsica, and Beretta platforms -- most commonly the 2.5L Iron Duke (used in S10), the 2.0L (early Cavalier), and the 2.2L (later Cavalier, Corsica, Beretta). These engines used compact distributor configurations suited to the four-cylinder firing order and ignition timing requirements.

The 4-cylinder EFI distributor market is smaller than the V6 and V8 segments but serves a real population of still-active vehicles, particularly S10 trucks and Cavalier/Corsica units maintained as economical daily drivers or work vehicles. Verify the OEM part number on your specific Chevrolet 4-cylinder application before ordering to confirm EP-1635-4 is the correct unit.

Ships complete with distributor cap and rotor.

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.

Founded in 1999 in Ningbo, Zhejiang Province, EP produces over 300 distributor models covering classic and modern GM, Ford, Chrysler, and international applications. Our GM EFI Distributor range is engineered as a direct OEM replacement for the factory Delco units -- same external dimensions, same connector configuration, same cap and rotor interface -- with improvements in housing material and component quality that address the known failure modes of the original distributors.

Wholesale buyers, Amazon resellers, and automotive service chains source directly from our factory, accessing OEM-quality replacement distributors at factory-direct pricing. OEM branding and private-label packaging are available for qualifying order volumes. EP is part of the Ever-Power Group, also producing worm reducers and a comprehensive range of mechanical transmission products.
