Cummins 8.3 Engine Parts

The Cummins C Series was introduced in 1985 with the 6C 8.3 liter engine. More durable that other models, this inline, 6-cylinder, medium-heavy duty engine was designed to last 150,000 miles between overhauls.

As Cummins started implementing electronic controls for its engines, the ISC (Interact System) started production in 1998, followed by the QSC (Quantum System) later on.

Cummins C Series diesel engines are used in various industrial, agricultural, and automotive applications.
