EP-1832 Optispark LT1 Distributor for Chevrolet Camaro 5.7L 1992-1994 Standard

The EP-1832 is a complete standard-specification Optispark LT1 distributor for the Chevrolet Camaro Z28 and Corvette C4 equipped with the LT1 5.7L V8 engine (1992-1994). The standard specification EP-1832 is the direct OEM-replacement counterpart to the billet-housing EP-8381, providing the same complete plug-and-play Optispark assembly at an accessible price point for general service applications.

The GM LT1 Optispark is a unique optical ignition system that replaced the conventional magnetic-pickup distributor in the fourth-generation Camaro and C4 Corvette. Mounted at the front of the engine and driven directly from the crankshaft, the Optispark provides a highly accurate crankshaft position reference signal to the PCM -- allowing the LT1 to deliver its characteristic combination of performance and fuel efficiency. The optical sensor inside the Optispark reads timing marks on a disc as it rotates, providing both cam synchronization and crankshaft position signals.

The EP-1832 ships as a complete ready-to-install assembly including the optical sensor, distributor cap, and rotor. OEM part number 10457702 is the primary factory reference for this application.

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.
