It ensures the combustion chamber remains airtight and allows for the controlled flow of high-pressure, high-temperature exhaust gases toward the manifold and the turbocharger. The kit includes an exhaust valve and retaining cones.
Used on Cummins Heavy Duty and Medium Duty engines (industrial, marine, automotive, and construction applications) in the ISC (8.3L), ISL / ISL9 / ISLE4 (8.9L), QSC8.3, QSL9, 6C8.3, B4.5, and ISF3.8 engine series. Models from approximately 2002 to the present.
Always verify using the Engine Serial Number (ESN).
The same ISC/ISL family can use different bowls depending on the application—road, industrial, or marine—or the position of the filter housing.
The ESN remains the most important check,
because the same engine model can be fitted with different
parts depending on the year of manufacture or the CPL.
